    Ninety five surface scrape samples were collected at the Ravenglass saltmarsh and analysed for radionuclides by alpha spectrometry ((238)Pu and (239,240)Pu), gamma spectrometry ((241)Am and (137)Cs) and liquid scintillation counting ((241)Pu). Both (241)Am and (137)Cs activities are compared with those reported by Horrill [1983. Concentrations and spatial distribution of radioactivity in an ungrazed saltmarsh. In: Coughtrey, P.J.

    In landscapes with extensive mining history, saltmarshes can become sinks for contaminants that are vulnerable to release with sea-level rise and increased storminess. Given the prolonged residence time of heavy metals in the environment, data is urgently required to contextualise the impacts of past and present mining and pollution events and provide a baseline against which to assess Water Framework Directive (WFD) (2000/60/EC) compliance within an integrated catchment management framework. The geology of east Cornwall, UK (with intrusions of granite into the surrounding sedimentary rocks) was favourable for a prosperous mining industry, although large scale operations did not start until about 1830. Tin, cooper, lead and tungsten were the most important ores in the region. In order to quantify the spatial and temporal extent of contamination from past mining, sediment cores were collected from three saltmarshes, namely: Antony Marsh and Treluggan Marsh on the Lower Basin of River Lynher, and Port Eliot Marsh on the Lower Basin of River Tiddy. Core sections at 1 cm intervals were analysed by gamma-ray spectrometry for Pb-210, Ra-226, Cs-137 and Am-241, and the well-established Constant Rate of Supply (CRS) model was employed to derive Pb-210 geochronology with bomb-derived Cs-137 and Am-241 as independent chronological markers. The geochronological data provided the sedimentary accumulation and temporal context for the study. In terms of sediment quality with respect to mining pollution, core sections were analysed using Q-ICP-MS techniques and, additionally, WD-XRF instrumentation at Plymouth University. Measurements were performed for target elements that are normally associated with mining and smelting activities (e.g. Pb, Cu, Sn, Zn, Cr, Cd, etc.), and lithogenic elements (e.g. Fe, Al, Ti) that allow enrichment factors for the anthropogenically-derived elements to be determined. The grain size distribution was determined to identify storminess events and to

    Tidal saltmarshes in the UK, and especially in the estuaries of southeast England, have been subject to degradation and erosion over the last few decades, primarily caused by sea-level rise and coastal squeeze due to fixed coastal defences. This is of great concern to a range of coastal stakeholders due to the corresponding loss of functions and services associated with these systems. The coastal defence role that saltmarshes play is well established, and the importance of saltmarsh ecosystems as habitats for birds, fish, and other species is evidenced in the fact that a large proportion of saltmarsh in the southeast England is designated for its scientific and conservation significance. Sediment accumulation is critical for the maintenance of marsh elevation within the tidal frame and for delivery of the aforementioned functions and services. Although many studies have examined accumulation processes, key questions have yet to be fully tested through intensive field observations. One such question relates to the role of vegetation in mediating the retention of newly introduced sediment, as recent research has called into doubt the traditional view of halophytes significantly enhancing rates of sedimentation through wave dissipation. This study presents early results from a project designed to advance our understanding of the processes controlling sediment accumulation. The research focuses on the UK's first large-scale experimental managed flood defence realignment at Tollesbury, Blackwater estuary, Essex. The seawall protecting 21ha of reclaimed agricultural land was artificially breached in 1995 and saltmarsh has progressively developed as tidal exchange has introduced fine sediment into the site. Results from a 12 month monitoring campaign involving hierarchical two-week sediment trap deployments indicates that the role of vegetation in marsh development is less clear cut that previously thought. Gross sedimentation rates were generally higher in non

    Objectives To investigate adult occupational contact levels and risk of childhood leukaemia and non-Hodgkin's lymphoma (LNHL) in Seascale, an association found in other situations of rural population mixing (PM). Design Matched case–control study. Setting Seascale, Cumbria, UK. Participants For each case of LNHL recorded in patients under age 25 years during 1950–2006, up to 20 matched controls were chosen and parental occupational details obtained; an exception was a single working young adult, whose own occupation (and that of controls) was used. Primary outcome measures Contact levels of occupations were categorised as: low/medium (reference group), high or very high contact levels, as in previous studies, with provision for certain unusual occupations. In particular, specialist policemen responsible for security and access at the nearby Sellafield nuclear complex were allocated to the highest contact category, and those Sellafield employees who worked in controlled areas to the middle (high) category. Since of possible bias, unusual contact aspects noted in the main research and development (R&D) building were reserved for a supplementary analysis. ORs were calculated for the occupational contact levels. Results Compared to the reference group, the social class adjusted ORs for the high and very high contact categories were 8.18 (95% CI 0.95 to 70.33) and 14.90 (1.20 to 184.90), respectively, with a significant trend across the categories (p value=0.024). In the supplementary analysis with R&D workers moved to the very high contact category, the OR for the latter became 29.68 (2.12 to 415.79), and the p value for trend, 0.011. Conclusions The Seascale LNHL excess was most marked among those young people linked with high occupational contact levels; it is therefore not an exception to the pattern of family infection shown by other PM-related excesses. The findings have implications for the choice of controls in certain types of virus study. PMID:26243554

    Between 0900 GMT on 4th December and 0900 GMT on 6th December 2015, Atlantic Storm Desmond produced over 260 mm of rainfall in Cumbria, northwest England, representing a new UK 48 hour rainfall maximum, and breaking previous records set in 2005 and 2009. The December 2015 event resulted in a number of rivers significantly exceeding their 2009 levels, over-topping recently-commissioned flood defences, destroying bridges and flooding thousands of homes. Our research aim is to identify factors controlling significant geomorphological and sedimentary response during Storm Desmond along the upland sediment cascade including: Rattling Beck (Glenridding), a high gradient upland stream draining the flanks of Helvellyn (950 m.a.o.d.), and a 25km extended reach of the lower gradient piedmont Derwent River corridor downstream of Bassenthwaite Lake. Rattling Beck descends steeply from the eastern slopes of the Helvellyn massif draining across an alluvial fan into Lake Ullswater. On 5th December 2015 the village of Glenridding was severely impacted by flooding which deposited boulder-sized sediment within the centre of the village, completely blocking the pre-existing stream course and causing avulsion of waning stage flows through riverside properties. A major new sediment lobe was deposited on the existing alluvial fan downstream of the village, grading to the temporarily raised lake water level. Although a number of hillslope failures occurred in the higher catchment, the majority of the sediment transported by Rattling Beck and impacting the village was acquired within a 2km reach upstream of Glenridding through erosion of older glacial and alluvial sediments. Lateral channel erosion was enhanced by inability of flood flows to rework highly resistant boulder bar lag deposits related to a previous mine tailings dam failure in 1927. The River Derwent corridor extends for 30km downstream of Bassenthwaite Lake to the Irish Sea at Workington and has a sinuous course ranging in

    Estuarine wetland environments are at risk of significant transformation and loss due to sea-level rise and there is an increasing need to model such impacts. In a UK context, the relatively small size and morphological complexity of many estuaries necessitates a high spatial resolution but models must also be capable of efficient application over time scales of decades to centuries that correspond to widely used IPCC climate change scenarios. Little previous work of this kind has been carried out to date in the UK. An exception is the EU-funded BRANCH project, which simulated the drowning of intertidal topography, due to sea-level rise, and potential mudflat and saltmarsh responses to a change in inundation regime. However, this approach neglects the interplay of sea-level rise and sedimentation. Accordingly, this study investigates the potential of a more dynamic spatial landscape model to represent meso-scale impacts of sea-level rise on UK estuary environments. It takes as a starting point the Sea Level Affecting Marshes Model (SLAMM), which has been widely used in the USA. This is built around the US National Wetlands Inventory classification and adapting it to suit the tidal sedimentary environments and habitats typical of the UK requires changes to the source code. This paper presents results obtained from the application of an appropriately modified SLAMM code to contrasting estuarine environments in eastern England. The aim is to evaluate the ability of SLAMM to produce plausible projections of intertidal habitat change. The estuaries studied are covered by high-resolution altimetry data, and an extensive literature on their physical process regime allows the parameterisation of the various sub-models in SLAMM. A Matlab-based shell is used to perform an initial sensitivity analysis to better understand the nature of the modelled sea-level rise effects. This shell also provides a framework for Monte Carlo simulations forced by a set of UKCP09 sea-level rise

    Throughout the United Kingdom flood risk is a growing problem and a significant proportion of the population are at risk from flooding throughout the country. Across England and Wales over 5 million people are believed to be at risk from fluvial, pluvial or coastal flooding (DEFRA, 2013). Increasingly communities that have not dealt with flooding before have recently experienced significant flood events. The communities of Stockdalewath and Highbridge in the Roe catchment, a tributary of the River Eden in Cumbria, UK, are an excellent example. The River Roe has a normal flow of less than 5m3 sec-1 occurring 97 percent of the time however there have been two flash floods of 98.8m3 sec-1 in January 2005 and 86.9m3 sec-1 in May 2013. These two flash flood events resulted in the inundation of numerous properties within the catchment with the 2013 event prompting the creation of the Roe Catchment Community Water Management Group which aims are to deliver a sustainable approach to managing the flood risk. Due to the distributed rural population the community fails the cost-benefit analysis for a centrally funded flood risk mitigation scheme. Therefore the at-risk community within the Roe catchment have to look for cost-effective, sustainable techniques and interventions to reduce the potential negative impacts of future events; this has resulted in a focus on natural flood risk management. This research investigates the potential to reduce flood risk through natural catchment-based land management techniques and interventions within the Roe catchment; providing a scientific base from with further action can be enacted. These interventions include changes to land management and land use, such as soil aeration and targeted afforestation, the creation of runoff attenuation features and the construction of in channel features, such as debris dams. Natural flood management (NFM) application has been proven to be effective when reducing flood risk in smaller catchments and the

    Sea water contaminated with diluted radioactive effluent from the Windscale nuclear complex in Cumbria periodically floods low-lying grazing pasture around the estuaries of the rivers Esk, Irt and Mite near Ravenglass. During 1979, an experiment was carried out to measure the transfer of caesium-137 from grass to muscle in cows grazing these pastures. Grass samples were taken in a vivo external gamma-ray measurements were made on cattle. A very low transfer coefficient was found, less than 9 X 10-4 days kg-1 with a best estimate of 4 X 10-4 days kg-1, compared with a more usual value of around 3 X 10-2 days kg-1. The low transfer seems to occur because the bulk of the caesium-137 on the grass is bound to resuspended estuarine surface sediment deposited during flooding. In this form, the caesium-137 is only poorly absorbed across the gut of the grazing cattle.

    A variety of fission-product and transuranic radionuclides originating from the marine discharges from the fuel reprocessing plant at Sellafield, Cumbria are detectable in the bodies of black-headed gulls and their environment in the Ravenglass Estuary approximately 10 km to the south-west of the plant. The maximum concentrations of 95Nb, 137Cs and 239/240Pu detected in body tissues lie in the range 2 X 10(-3) to 1.5 X 10(-2) Bqg-1 wet weight. Many more radionuclides are detected in the regurgitated pellets and faeces produced by the gulls and have higher concentrations in the range 7 X 10(-3) to 1.7 Bqg-1 wet weight. The radionuclide contamination of the sediment produces a source of enhanced external gamma-ray exposure which can be measured directly. The available data on distributions and concentrations of radionuclides have been combined with simple dosimetry models to provide estimates of the radiation exposure of the birds. The total whole body dose rate to the adult birds from the contaminant radionuclides is approximately ten times that from the natural radiation background, while that to the developing eggs is approximately four times the natural background. The potential radiation exposure of the cells lining the alimentary tract could be much higher when contaminated food is in transit, but the long-term average exposure in this case is subject to uncertainty. The limited data on the effects of radiation exposure on birds do not indicate any response at dose rates below one hundred times that from the natural radiation background.(ABSTRACT TRUNCATED AT 250 WORDS)

    The aim of the North Cumbria Community Genetics Project is to establish a store of DNA, plasma, and viable cells from a cohort of around 8000 Cumbrian infants. To meet this objective, specimens of umbilical cord blood and tissue will be collected with maternal consent from babies born at the West Cumberland Hospital, Whitehaven over a five year period from January 1996. These samples will be used in a series of genetic and epidemiological studies investigating the interaction between genes, the environment, and health. There is little population movement in West Cumbria and so it will be possible to follow many of the babies throughout their childhood and to investigate the relationship between their genetic constitution and health outcome.

    2012-07-01

    It would be hard to imagine what West Cumbria, a remote area in the North West of England, would look like without the huge Sellafield nuclear complex. The site is owned by the Nuclear Decommissioning Authority (NDA) and managed by Nuclear Management Partners (NMP), an international private partnership consisting of URS from the United States of America, AMEC from the UK and AREVA from France. Today some 10,000 people work at Sellafield with many more employed through the site's supply chain, a large percentage of which is located directly in West Cumbria. The Government, through the NDA, has committed around pounds 1.5 billion a year for the next three years as we at NMP bring our vast global expertise and experience to deliver substantial improvements to the clean-up mission there. Of this total budget, more than Pounds 800 million a year is spent in that supply chain and around 30 percent of that goes directly to firms in West Cumbria. But the dependency on the nuclear industry is immense and, with the site now entering an extensive decommissioning programme, the threats to jobs, and therefore the local economy, is severe. While Sellafield provides wealth, there are areas of deep deprivation and worklessness. Consequently, Sellafield Ltd, NMP and NDA have partnered with the local community leaders and politicians to form Britain's Energy Coast, a strategic regeneration body driving economic improvements and projects to deliver a vibrant economy for West Cumbria, long into the future. While the threats to our economy are real, the opportunities are potentially transformational. The UK is on the brink of a nuclear renaissance and, if we are successful through the Energy Coast programme, West Cumbria will become the hub, not only of the nuclear industry, but also of green energy production in the UK, with obvious benefits to our local economy. But to achieve this, Sellafield and its new owners are having to change the opportunistic ways of the past to provide a new

    The quantification of carbon sequestration rates in coastal ecosystems is required to better realise their potential role in climate change mitigation. Through accurate valuation this service can be fully appreciated and perhaps help facilitate efforts to restore vulnerable ecosystems such as saltmarshes. Vegetated coastal ecosystems are suggested to account for approximately 50% of oceanic sedimentary carbon despite their 2% areal extent. Saltmarshes, conservatively estimated to store 430 ± 30 Tg C in surface sediment deposits, have experienced extensive decline in the recent past; through processes such as land use change and coastal squeeze. Saltmarsh habitats offer a range of services that benefit society and the natural world, making their conservation meaningful and beneficial. The associated costs of restoration projects could, in part, be subsidised through payment for ecosystem services, specifically Blue carbon. Additional storage is generated through the (re)vegetation of mudflat areas leading to an altered ecosystem state and function; providing similar benefits to natural saltmarsh areas. The Eden Estuary, Fife, Scotland has been a site of saltmarsh restoration since 2000; providing a temporal and spatial scale to evaluate these additional benefits. The study is being conducted to quantify the carbon benefit of restoration efforts and provide an insight into the evolution of this benefit through sites of different ages. Seasonal sediment deposition and settlement rates are measured across the estuary in: mudflat, young planted saltmarsh, old planted saltmarsh and extant high marsh areas. Carbon values being derived from loss on ignition organic content values. Samples are taken across a tidal cycle on a seasonal basis; providing data on tidal influence, vegetation condition effects and climatic factors on sedimentation and carbon sequestration rates. These data will inform on the annual characteristics of sedimentary processes in the estuary and be

    Long term spatial and temporal variations in radionuclide activity have been measured in a contaminated ungrazed saltmarsh near Ravenglass, Cumbria. Over a twenty-five year period there has been a decrease in activity concentration with (106)Ru and (137)Cs showing the highest rate of change followed by Pu alpha and (241)Am. A number of factors contribute to the reduction with time; including radiological half lives, discharge and remobilisation. For (241)Am the lower reduction rate is partially due to ingrowth from (241)Pu and partially as a result of transport of sediment from the offshore Irish Sea mud patch. Considerable spatial variation for the different radionuclides was observed, which with time became less defined. The highest activity concentrations of long-lived radionuclides were in low energy areas, typically where higher rates of sedimentation and vegetation occurred. The trend was reversed for the shorter lived radionuclide, (106)Ru, with higher activity concentrations observed in high energy areas where there was frequent tidal inundation. Surface scrape samples provide a pragmatic, practical method of measuring sediment contamination over large areas and is a sampling approach adopted by most routine environmental monitoring programs, but it does not allow for interpretation of the effect of variation in sedimentation rates. This paper proposes a method for calculating indicative sedimentation rates across the saltmarsh using surface scrape data, which produces results consistent with values experimentally obtained.

    Many saltmarsh platforms in New England and other northern climates (e.g. Canada, northern Europe) exhibit poor drainage, creating waterlogged regions where short-form Spartina alterniflora dominates and stagnant pools that experience tidal exchange only during spring tides and storm-induced flooding events. The processes related to pool formation and tidal creek incision (via headward erosion) that may eventually drain these features are poorly understood, however it has been suggested that an increase in pool occurrence in recent decades is due to waterlogging stress from sea-level rise. We present evidence here that saltmarshes in Plum Island Estuary of Massachusetts are keeping pace with sea-level rise, and that the recent increase in saltmarsh pool area coincides with changes in drainage density from a legacy of anthropogenic ditching (reversion to natural drainage conditions). Gradients, in addition to elevation and hydroperiod, are critical for saltmarsh pool formation. Additionally, elevation and vegetative changes associated with pool formation, creek incision, subsequent drainage of pools, and recolonization by S. alterniflora are quantified. Pool and creek dynamics were found to be cyclic in nature, and represent platform elevation in dynamic equilibrium with sea level whereby saltmarsh elevation may be lowered (due to degradation of organic matter and formation of a pool), however may be regained on short timescales (101-2 yr) with creek incision into pools and restoration of tidal exchange. Rapid vertical accretion is associated with sedimentation and S. alterniflora plant recolonization.

    Although saltmarshes are thought to enhance the productivity of open estuarine waters, the mechanism by which energy transfer occurs has been debated for decades. One possible mechanism is the transfer of saltmarsh production to estuarine waters by vagile fishes and invertebrates. Monthly estimates of fish standing stock, net fish ingress, and predation were used to develop a biomass budget to estimate annual production of fishes and the relative yield to predatory fish, birds, and direct migration to the estuary. Annual production of saltmarsh fishes was estimated to be 31.0 g m-2 saltmarsh, which falls within the range of previously reported values for estuarine fish communities. The relative yields were 12 to 20% to piscivorous fishes, 8 to 13% to piscivorous birds, and 18 to 29% to export. Annual export of fish biomass was 5.6 g fish m-2 saltmarsh, representing about 1 to 2% of saltmarsh primary production. Saltmarsh fishes convert marsh production to high-quality vagile biomass (fishes concentrate energy, protein, and nutrients as body mass) and move this readily useable production to the estuary, providing an efficient link between saltmarshes and estuarine predators. ??

    Saltmarshes are globally important environments which, though occupying < 4% of the Earth's surface, provide a range of ecosystem services. Yet, they are threatened by sea level rise, human population growth, urbanization and pollution resulting in degradation. To compensate for this habitat loss many coastal restoration projects have been implemented over the last few decades, largely driven by legislative requirements for improved biodiversity e.g. the EU Habitats Directive and Birds Directive. However, there is growing evidence that restored saltmarshes, recreated through the return to tidal inundation of previously drained and defended low-lying coastal land, do not have the same species composition even after 100 years and while environmental enhancement has been achieved, there may be consequences for ecosystem functioning This study presents the findings of a comparative analysis of detailed sediment structure and hydrological functioning of equivalent natural and de-embanked saltmarsh sediments at Orplands Farm, Essex, UK. 3D x-ray CT scanning of triplicate undisturbed sediment cores recovered in 2013 have been used to derive detailed volumetric reconstructions of macropore structure and networks, and to infer differences in bulk microporosity between natural and de-embanked saltmarshes. These volumes have been further visualised for qualitative analysis of the main sediment components, and extraction of key macropore space parameters for quantified analysis including total porosity and connectivity, as well as structure, organisation and efficiency (tortuosity) of macropore networks. Although total porosity was significantly greater within the de-embanked saltmarsh sediments, pore networks in these samples were less organised and more tortuous, and were also inferred to have significantly lower micro-porosity than those of the natural saltmarsh. These datasets are applied to explain significant differences in the hydraulic behaviour and functioning

    Ascomycetous fungi are the principal drivers of the decomposition of shoots of smooth cordgrass (Spartina alterniflora). Shoots of smooth cordgrass move into the saltmarsh food web via the decomposition system. Therefore, influences on saltmarsh ascomycetes by pollutants of saltmarshes could have far-reaching impacts. Earlier examination of impacts of severe contamination of a Georgia saltmarsh by mercury and polychlorinated biphenyls (PCBs) revealed little or no influence of the toxicants on living standing crops or sexual productivities of cordgrass ascomycetes. Extension of the examination of saltmarsh-ascomycete response to sites containing other toxic pollutants (the chlorinated organocyclic insecticide toxaphene; chromium, copper, and lead; and polycyclic aromatic hydrocarbons [PAHs]) has shown that none of the additional toxicants engendered saltmarsh-fungal responses in the form of reduced living standing crops or sexual productivities. Thus the ascomycetes of the cordgrass-decay system appear to be as resistant to anthropogenic-pollutant poisoning as smooth cordgrass itself. Unless the fungal and plant resistance mechanisms involve degradation of the toxicants, this may imply that saltmarshes are especially dangerous as receiving sites for toxic waste because they may have the potential to readily move toxicants into the food web.

    Modeling studies of estuary circulation show great sensitivity to the water exchange into and out of adjacent marshes, yet there is significant uncertainty in resolving the processes governing marsh surface flow. The objective of this study is to measure the estuary channel-to-saltmarsh pressure gradient and to guide parameterization for how it affects the surface flow in the high marsh. Current meters and high-resolution pressure transducers were deployed along a transect perpendicular to the nearby Little Ogeechee River in a saltmarsh adjacent to Rose Dhu Island near Savannah, Georgia, USA. The vertical elevations of the transducers were surveyed with static GPS to yield high accuracy water surface elevation data. It is found that water level differences between the Little Ogeechee River and neighboring saltmarsh are up to 15 cm and pressure gradients are up to 0.0017 m of water surface elevation change per m of linear distance during rising and falling tides. The resulting Little-Ogeechee-River-to-saltmarsh pressure gradient substantially affects tidal velocities at all current meter locations. At the velocity measurement station located closest to the Little Ogeechee River bank, the tidal velocity is nearly perpendicular to the bank. At this location, surface flow is effectively modeled as a balance between the pressure gradient force and the drag force due to marsh vegetation and bottom stress using the Darcy-Weisbach/Lindner's equations developed for flow-through-vegetation analysis in open channel flow. The study thus provides a direct connection between the pressure gradient and surface flow velocity in the high marsh, thereby overcoming a long-standing barrier in directly relating flow-through-saltmarsh studies to flow-through-vegetation studies in the open channel flow literature.

    The influence of the saltmarsh plant Halimione portucaloides and the level of sediment metal contamination on the distribution of microbial communities were investigated in two Portuguese estuarine systems with different degrees of metal contamination: the Cavado (41.5 N; 8.7 W) and Sado estuaries. In the Sado, two saltmarshes were studied: Lisnave (38.4 N; 8.7 W) and Comporta (38.4 N; 8.8 W). A PCR rDNA-DGGE approach and direct microscopic counts of DAPI-stained cells were applied to study the biodiversity and abundance of prokaryotic communities. Sediment characteristics and metal concentrations (Cd, Cr, Cu, Fe, Pb, Mn, Ni and Zn) were also evaluated to identify possible environmental pollution constraints on spatial and temporal microbial dynamics. Redundancy analysis (RDA) revealed that the Lisnave saltmarsh microbial community was usually associated with a higher degree of metal contamination, especially the metal Pb. In clear contrast, the Cavado estuary microbial assemblage composition was associated with low metal concentrations but higher organic matter content. The Comporta saltmarsh bacterial community clustered in a separate branch, and was associated with higher levels of different metals, such as Ni, Cr and Zn. Additionally, the microbial community structure of the Lisnave and Cavado showed a seasonal pattern. Moreover, microbial abundance correlated negatively with metal concentrations, being higher at the Cavado estuarine site and with general higher counts in the rhizosediment. These findings suggest that increased metal concentrations negatively affect the abundance of prokaryotic cells and that saltmarsh plants may have a pivotal role in shaping the microbial community structure.

    Analyses of saltmarsh ecosystem services have been particularly focused on the capacity of mitigating climate change effects to cope with rising sea levels and concerning flood management. Nevertheless, ecosystem stability is vital for accurate service delivery, but land-use changes and coastal erosion are affecting saltmarshes. This provides the background for one of the primary arguments for protecting saltmarshes. Landscape metrics were selected according to shape, complexity, and connectivity parameters, and added to average elevation and distance to the coast, for two years - 1972 and 2010. We developed an equation that measures coastal protection, taking into account the results of PCA and the percentage of explained variation of each component (coastal defence index: ES_CoastDef). Three saltmarshes located in the Algarve region, Portugal, were selected to apply the coastal defence index. Individual patches were analysed according to saltmarsh typologies. Results revealed that every saltmarsh decreased its coastal defence from 1972 to 2010; changes in shape and connectivity metrics affect mostly the index performance. In 1972, natural saltmarshes offered a better coastal defence than the other typologies, but in 2010 formerly reclaimed saltmarshes comprised higher values of coastal defence. Positive evolutions in terms of reclaimed saltmarshes have enabled them to provide coastal defence ecosystem services. Thus, through this index it is possible to outline target coastal defence parameters and design strategies for their conservation and consider ecological restoration.

  4. Monitoring the pollution from a pyre used to destroy animal carcasses during the outbreak of Foot and Mouth Disease in Cumbria, United Kingdom

    The recent outbreak of Foot and Mouth Disease has affected many parts of the UK but none more so than Cumbria, which has had the highest proportion of infected premises. From the beginning of the outbreak, pyres were used to destroy the animal carcasses, however, over time this policy was questioned due to the growing concern about the levels of pollution being emitted from the pyres and their potential impact on human health. Of particular concern were the potential levels of dioxins being emitted from the materials used to construct the pyres as well as from the combustion of the animal carcasses. This paper describes a monitoring campaign that measured the air concentrations of key pollutants from a pyre in Cumbria. Measurements were taken close to residences downwind of the pyre using a mobile laboratory equipped to sample respiratory irritants (SO 2, PM 10 and NO 2) and carcinogens (VOCs and particle-bound PAHs). Measurements of speciated dioxins, furans and PAHs were made on samples collected using a high-volume air sampler co-located with the laboratory. Results from the campaign showed that although the levels of pollutants such as SO 2, PM 10, dioxins, furans and PAHs were clearly elevated above normal background concentrations, the levels were unlikely to cause a substantial exceedance of air quality standards. Moreover, the work showed that for the local residents downwind of this particular pyre, all but the most sensitive individuals (i.e. severe asthmatics and sufferers of lung disease) were unlikely to experience any significant health effects.

    Salt marshes are coastal ecosystems which play a large role in the bio-geomorphological evolution of intertidal areas. The dense stands of halophytic plants which populate salt-marsh systems largely contribute to govern their dynamics, influencing marsh hydrodynamics and sediment transport through enhanced flow resistance and settling, and direct particle capture by plant stems. In addition, plants are known to increase vertical accretion through direct organic accretion. Looking across the salt-marsh landscape can one see the signatures of feedbacks between landscape and biota? Field evidence and the results of biomorphodynamic models indeed show that the interplay between physical and biological processes generates some striking biological and morphological patterns at different scales. One such pattern, vegetation zonation, consists in a mosaic of vegetation patches, of approximately uniform composition, displaying sharp transitions in the presence of extremely small topographic gradients. Here we extend the model proposed by Marani et al. (2013) to a two-dimensional framework, furthermore including the effect of direct capture of sediment particles by plant stems. This allows us to account for the effect of the drainage density of tidal networks on the observed biogeomorphic patterns and to model the coupled evolution of marsh platforms and channel networks cutting through them. A number of different scenarios have been modelled to analyze the changes induced in bio-geomorphic patterns by plants with different characteristics, within marshes characterized by different drainage densities, or subjected to changing environmental forcing such as rates of relative sea level rise and sediment supply. Model results emphasize that zonation patterns are a signature of bio-geomorphic feedbacks with vegetation acting as a landscape constructor which feeds back on, directly alters, and contributes to shape tidal environments. In addition, model results show that

    Few studies have empirically examined the suite of mechanisms that underlie the distributional shifts displayed by organisms in response to changing climatic condition. Mangrove forests are expected to move inland as sea-level rises, encroaching on saltmarsh plants inhabiting higher elevations. Mangrove propagules are transported by tidal waters and propagule dispersal is likely modified upon encountering the mangrove-saltmarsh ecotone, the implications of which are poorly known. Here, using an experimental approach, we record landward and seaward dispersal and subsequent establishment of mangrove propagules that encounter biotic boundaries composed of two types of saltmarsh taxa: succulents and grasses. Our findings revealed that propagules emplaced within saltmarsh vegetation immediately landward of the extant mangrove fringe boundary frequently dispersed in the seaward direction. However, propagules moved seaward less frequently and over shorter distances upon encountering boundaries composed of saltmarsh grasses versus succulents. We uniquely confirmed that the small subset of propagules dispersing landward displayed proportionately higher establishment success than those transported seaward. Although impacts of ecotones on plant dispersal have rarely been investigated in situ, our experimental results indicate that the interplay between tidal transport and physical attributes of saltmarsh vegetation influence boundary permeability to propagules, thereby directing the initial phase of shifting mangrove distributions. The incorporation of tidal inundation information and detailed data on landscape features, such as the structure of saltmarsh vegetation at mangrove boundaries, should improve the accuracy of models that are being developed to forecast mangrove distributional shifts in response to sea-level rise.

The model allows us describe the coupled evolution of marsh platforms and channel networks cutting through them. A number of different scenarios were modelled to analyze the changes induced in bio-geomorphic patterns by plants with different characteristics, within marshes characterized by different drainage densities, or subjected to changing environmental forcing such as rates of relative sea level rise and sediment supply. Model results emphasize that zonation patterns are a signature of bio-geomorphic feedbacks with vegetation acting as a landscape constructor which feeds back on, directly alters, and contributes to shape tidal environments. In addition, model results show that biogeomorphic feedbacks critically affect the response and the resilience of salt-marsh landscapes to changes in the environmental forcing.

    During the 1990s, Florida has continued to make important strides in managing salt marshes for both mosquito control and natural resource enhancement. The political mechanism for this progress continues to be interagency cooperation through the Florida Coordinating Council on Mosquito Control and its Subcommittee on Managed Marshes (SOMM). Continuing management experience and research has helped refine the most environmentally acceptable source reduction methods, which typically are Rotational Impoundment Management or Open Marsh Water Management. The development of regional marsh management plans for salt marshes within the Indian River Lagoon by the SOMM has helped direct the implementation of the best management practices for these marshes. Controversy occasionally occurs concerning what management technique is most appropriate for individual marshes. The most common disagreement is over the benefits of maintaining an impoundment in an "open" vs. "closed" condition, with the "closed" condition, allowing for summer mosquito control flooding or winter waterfowl management. New federal initiatives influencing salt-marsh management have included the Indian River Lagoon-National Estuary Program and the Pesticide Environmental Stewardship Program. A new Florida initiative is the Florida Department of Environmental Protection's Eco-system Management Program with continuing involvement by the Surface Water Improvement and Management program. A developing mitigation banking program has the potential to benefit marsh management but mosquito control interests may suffer if not handled properly. Larvicides remain as an important salt-marsh integrated pest management tool with the greatest acreage being treated with temephos, followed by Bacillus thuringiensis israelensis and methoprene. However, over the past 14 years, use of biorational larvicides has increased greatly.

    Nearly all previous studies of saltmarsh-nesting Common Terns on the east coast of the United States have concluded that tidal saltmarshes were suboptimal or marginal breeding habitats. Questioning that conclusion, we analyzed patterns of both saltmarsh and nonmarsh colony use (stability, movement, establishment, abandonment, and size) obtained during 5 yr of annual helicopter censuses of all Common and Roseate terns breeding on Long Island, New York. We found 1900-3600 pairs at 10-33 saltmarsh and 22-30 nonmarsh sites; there were few biologically important differences between Common Terns nesting at marsh and at nonmarsh sites. We did find that (1) marsh sites and colony sizes increased through the study period; (2) both marsh and nonmarsh colonies grew with duration of occupancy; (3) smaller marsh and nonmarsh colonies (<50 pairs) usually lasted only 12 yr, while larger colonies were equally likely to persist for 1, 2, 3, 4, or 5 yr; (4) numbers of marsh and nonmarsh sites used each year were generally unrelated to population sizes; (5) 5yr sites composed only 10.6% of total marsh and 17.6% of total nonmarsh sites; (6) the mean sizes of both newly established and about-to-be-abandoned colonies were smaller than the mean sizes of all others when averaged between but not within years; (7) most previously occupied sites, once abandoned, remained so for only 1 yr, and most new sites were occupied for only a single year; (8) annual turnover rates were 32%-49% for both marsh and nonmarsh sites; (9) marsh and nonmarsh breeding populations were correlated each year, allowing estimation of the total Long Island population to within +4% by censusing only the 20-25% in saltmarshes. Roseate Tern data were few, especially in marshes, obviating marsh-nonmarsh comparisons, except that Roseates failed to persist in saltmarshes, and their overall mean colony sizes across the same numbers of years' occupancy were usually smaller than Commons', although their turnover rates were

  12. Tidal events and salt-marsh structure influence black mangrove (Avicennia germinans) recruitment across an ecotone.

    2012-07-01

    Field experiments were conducted at a black mangrove-salt-marsh ecotone in southwest Florida (U.S.A.) to investigate retention of propagules of the black mangrove, Avicennia germinans, by salt-marsh plants as a mechanism of facilitation operating on recruitment success at landward boundaries. Buoyant A. germinans propagules are dispersed by tides, and stranding is required for establishment; therefore, processes that enable stranding should facilitate mangrove recruitment. We expected the physical structure of salt-marsh vegetation to define propagule retention capacity, and we predicted that salt-marsh plants with distinct growth forms would differentially retain propagules. Experimental monoculture plots (1 m2) of salt-marsh plants with different growth forms (Sporobolus virginicus [grass], Sesuvium portulacastrum [succulent forb], and Batis maritima [succulent scrub]) were created, and A. germinans propagules were emplaced into these plots and monitored over time. For comparison, propagules were also placed into natural polyculture plots (1 m2). Polyculture plots contained at least two of the salt-marsh plant taxa selected for monoculture treatments, and S. virginicus was always present within these polyculture plots. Natural polyculture plots retained 59.3% +/- 11.0% (mean +/- SE) of emplaced propagules. Monocultures varied in their propagule retention capacities with plots of S. virginicus retaining on average 65.7% +/- 11.5% of transplanted propagules compared to 7.2% +/- 1.8% by B. maritima and 5.0% +/- 1.9% by S. portulacastrum. Plots containing S. virginicus retained a significantly greater percentage of emplaced propagules relative to the two succulent salt-marsh taxa. Furthermore, propagule entrapment, across all treatments, was strongly correlated with salt-marsh structure (r2 = 0.6253, P = 0.00001), which was estimated using an indirect quantitative metric (lateral obstruction) calculated from digital images of plots. Overall, our findings imply that

    The saltmarsh-mangrove interface generally constitutes the landward boundary for the grey mangrove Avicennia marina var. australasica, the most widespread species on southeast Queensland shores. A. marina produces buoyant propagules, which are dispersed by tidal waters, only infrequently transported to saltmarsh by the highest spring tides. We predicted that runnelling, a form of habitat modification for mosquito control, transports and deposits mangrove propagules to saltmarsh because the runnels carry low-amplitude tides that would not normally inundate higher regions of the marsh. To test this, groups of marked A. marina propagules were released at three runnelled saltmarshes in southeast Queensland during high-amplitude, flooding and low-amplitude, non-flooding tidal events. The distance propagules were transported from their original starting positions on the saltmarsh-mangrove interface was measured and analysed to detect differences among groups at different distances from runnels. Groups of propagules released within 10 m of a runnel were always transported significantly further from the starting position and further up the saltmarsh shore after both flooding and non-flooding tides than any other groups. In addition, the pattern of stranding on saltmarsh for significantly different groups was closely associated with the path of runnel construction so that propagules were located either in the runnel or in depressions linked to the runnel that had been isolated mosquito-breeding pools prior to runnelling. Observations of A. marina plants at other runnelled sites suggest that propagules transported by runnels can establish and develop to maturity, at least in depressions and runnels, in saltmarsh. The fact that runnels transport propagules to regions of the saltmarsh beyond their normal limits of dispersion suggests a possible advantage for landward extension of the intertidal distribution of A. marina at runnelled sites and should be considered in saltmarsh

    In the past decades, regular spatial patterns have been described in a wide range of ecosystems, ranging from arid lands to boreal peat lands. Pattern formation mechanisms in many of these ecosystems are caused by scale-dependent interactions between organisms and geophysical processes, causing facilitation between organisms at small spatial scale, but inhibition at larger spatial scales. This conforms to the activation-inhibition principle laid out by Alan Turing in 1953. We present a combination of experimental and modeling studies on early salt-marsh development that indicate that similar scale-dependent interactions determine the establishment of salt-marsh vegetation and early geomorphological development of the marsh. Based on these studies, we argue that the early development of salt-marsh ecosystems is characterized by a Turing instability, placed into a complex landscape setting.

    Saltmarshes have been depleted historically, and cumulative stressors threaten their future persistence. We examined experimentally how nutrient availability (high vs. low) affects the responses of Spartina maritima to increased inundation in two mineral soil types (low vs. medium organic). Increased inundation, one of the effects of accelerated sea level rise, had negative effects on most plant growth parameters, but the magnitude varied with soil and nutrient levels, and between plants from different locations. Average differences between inundation treatments were largest at high nutrient conditions in low organic matter soils. We conclude that saltmarsh vegetation would be more drastically affected by increased inundation in low than in medium organic matter soils, and especially in estuaries already under high nutrient availability. This knowledge enhances the prediction of changes at the foreshore of saltmarshes related to sea level rise, and the development of site-specific conservation strategies.

    Salt-marshes are under increasing threat, particularly from sea-level rise and increased wave action associated with climate change. The development and stability of these valuable habitats largely depend on complex interactions between biotic and abiotic processes operating at different scales. Also, interactions between biotic and abiotic processes drive internal morphological change in salt-marshes. In this paper we used a biogeomorphological approach to assess the impact of biological activities and interactions on salt pan formation in Sarcocornia-dominated salt marshes. Salt pans represent a key physiographic feature of salt-marshes and recent studies hypothesized that biogeomorphic processes could be related to salt pan formation in SW Atlantic salt-marshes. The glasswort Sarcocornia perennis is one of the dominant plants in the salt-marshes of the Bahía Blanca Estuary (Argentina) where they form patches up to 8 m in diameter. These salt-marshes are also inhabited in great densities by the burrowing crab Neohelice (Chasmagnathus) granulata whose bioturbation rates are among the highest reported for salt-marshes worldwide. A set of biological interactions between N. granulata and S. perennis appears to be responsible for salt pan development in these areas which has not been described elsewhere. The main objective of this work was to determine the ecological interactions occurring between plants and crabs that lead to salt pan formation by using field-based sampling and manipulative experiments. Our results showed that S. perennis facilitated crab colonization of the salt-marsh by buffering otherwise stressful physical conditions (e.g., temperature, desiccation). Crabs preferred to construct burrows underneath plants and, once they reach high densities (up to 40 burrows m- 2), the sediment reworking caused plant die-off in the central area of patches. At this state, the patches lose elevation and become depressed due to the continuous bioturbation by crabs

    Saltmarsh restoration undoubtedly provides environmental enhancement, with vegetation quickly re-establishing following the breach of sea walls and subsequent tidal inundation of previously defended areas. Yet evidence increasingly suggests that the restored saltmarshes do not have the same biological characteristics as their natural counterparts (Mossman et al. 2012) and this may be in part be due to physicochemical parameters at the site including anoxia and poor drainage. Hence, restored saltmarshes may not offer the range and quality of ecosystem services anticipated. These environments will have been 'disturbed' by previous land use and there is little understanding of the impacts of this disturbance on the wider hydrogeomorphic and biogeochemical functioning in restored saltmarshes and the implications for saltmarsh vegetation development. This study examines linkages between physical sediment characteristics, sediment structure (using X-ray microtomography), sub-surface hydrology (using pressure transducers and time series analysis), and sediment and porewater geochemistry (major and trace elements, major anions) in sediment cores collected from undisturbed saltmarshes and those restored by de-embankment. Sub-surface sediments in restored saltmarshes have lower organic matter content, lower moisture content and higher bulk density than undisturbed sites. Using X-ray tomography a clear horizon can be observed which separates relict agricultural soils at depth with less dense and structureless sediments deposited since de-embankment. Ratios of open to closed pore space suggest that while undisturbed saltmarshes have the highest porosity, restored saltmarshes have larger void spaces, but limited pore connectivity. Sub-surface hydrological response to tidal flooding was subdued in the restored compared to the undisturbed site, suggesting that porewater flow may be impeded. Time series analysis indicated that flow pathways differ in restored saltmarsh sediments

    Seaborne sediments deposited in the estuaries of the Esk, Duddon, Leven and Kent have been analysed for fission products and actinides discharged in waste from the Sellafield processing works in west Cumbria, and the values compared with the generally expected values due to fallout from atmospheric nuclear weapons tests. Analyses of tissues from sheep grazing the marshes of these estuaries show that the internal radiation dose of the general public through eating mutton or liver from these animals would be at most a few percent of recommended limits. Analytical data are presented on the actinide content of beef cattle, and on potato crops grown under field conditions; these data show that, as with the sheep data, the radiation dose to the consumer would be small.

    The salt-marshes of the Baie de l'Aiguillon (Western France) are among the largest of Western Europe. Thanks to exceptional historical data, including old maps, manuscripts and aerial photographs, we propose one of the first long-term accurate cartographies of such a large salt-marsh, dating back to the beginning of the 18th century. Like other salt-marshes in Western Europe, including those of the Mont Saint-Michel Bay (France), we found that they are expanding for the three last decades. However, our historical analysis also reveals that the area of these salt-marshes shrinked by two thirds over the last three centuries, due to massive land-reclamations starting from the mid-17th century. As revealed by historical testimonies and archeological remains, we also demonstrated that these salt-marshes were actively mowed as soon as the 1700s. In consequence, the oldest and the non-used parts of such salt-marshes correspond to very restricted patches that may present a high conservation stake. In the context of massive land-use and land-cover changes along the European coastal zones, historical analyses exploring long-term changes and historical uses of coastal habitats may help to identify old and natural patches of coastal habitats. Salt-marshes, that are easy to map and monitor, are good candidates for such investigations.

    Will mangrove encroachment into saltmarshes affect saltwater mosquito habitats? To address this, we synthesized information from two perspectives: 1) at a detailed level, the immature mosquito habitat within mangroves; 2) at a more general or regional level, changes due to mangrove expansion into saltmarshes. This is a synthesis of two research projects. One showed that mosquito larval habitats in mangroves are complex, related to the detailed interactions between topography and tidal patterns and that not all parts of a mangrove forest are suitable habitat. The other, based on remote sensing and analysis of rainfall data, showed that mangrove encroachment in eastern Australia is related to both climate and human land use over several decades (1972-2004). An important question emerged: when mangroves encroach into saltmarshes will they displace saltmarsh immature mosquito habitats or will they replace them with mangrove ones? There is no simple answer: it will vary with climate change and sea level scenario and how these affect the system. We conclude that mosquito management, which is locally implemented, needs to be integrated with land use planning systems, which often operate at a more general level. PMID:24581363

  1. Comparing Aedes vigilax Eggshell Densities in Saltmarsh and Mangrove Systems with Implications for Management.

    Aedes vigilax (Skuse), a nuisance and disease vector, is prolific in intertidal wetlands in Australia. Aedine mosquitoes oviposit directly onto substrate. The eggshells are relatively stable spatially and temporally, providing an estimate of mosquito larval production. The aims of the research were to compare, at a general level, oviposition in mangroves and saltmarshes, and to compare oviposition between different habitats within mangroves and saltmarshes. The results indicated that there were no significant differences between production in mangrove and saltmarsh overall. However, within each system there were significant differences between habitat classes, with mangrove hummocks being the most productive. All classes, except for fringing mangrove forests, produced sufficient densities of eggshells (>0.05/cc) to warrant concern. While mosquito production in mangroves is known, the significantly higher production rates in the mangrove hummock habitats had not been demonstrated. This warrants improved management strategies that both specifically target these parts of mangrove systems and, secondly, addresses the longer-term potential for mangrove hummock habitats developing in the future; such as, in response to sea level rise and mangrove encroachment into saltmarsh. A strategy to increase tidal flushing within the systems would improve water quality and mitigate adverse impacts while providing a source reduction outcome.

    Intertidal sediments in north-west England contain enhanced levels of artificial radionuclides due to the authorized release of low-level liquid waste from the Sellafield reprocessing site. In this paper, the behaviour of 99Tc, 137Cs, 237Np, 238Pu, 239Pu, 240Pu, 239+240Pu and 241Am in an intertidal marsh sediment is described. The radionuclide data, together with stable element data, allow detailed interpretation of the behaviour of these artificial radionuclides in a natural environment. For 241Am and 239+240Pu, for which the Sellafield discharge history is well known, the distributions down the sediment core show a high correlation with the Sellafield discharge history. The sediment profiles for other less widely studied radionuclides, 99Tc and 237Np, have been examined in relation to both the post-1978 published discharge histories and the behaviour of other Sellafield-derived radionuclides in the core. There is strong evidence that significant post-depositional remobilization of a proportion of the most labile elements, 237Np, 137Cs and 99Tc, is occurring at the marsh.

  5. A review of the specialties that care for inpatient burns and smoke inhalation in the English counties of Lancashire and South Cumbria.

    Prevention is by far the best strategy to minimise the burden of burns and smoke inhalation injuries on public health. However, it is inevitable that some injuries will occur despite the best attempts to prevent them. We must, therefore, optimise treatment in order to restore individuals to the best possible condition. Previous experience has shown that a wide range of specialties, many of which are untrained in burn care medicine, are involved in the care of inpatient burns/smoke inhalation victims in the UK. In light of this, a local review of which specialties care for such injuries was conducted for the population of Lancashire and South Cumbria in the north-west of England. Using population-based health authority data from 1997 to 1999, all Hospital Episodes relating to a primary diagnosis of burns or smoke inhalation were ascertained. The results showed that 41% of all burns episodes were treated by specialties other than burns/plastics. The short lengths of stay in non-plastics/burns specialties suggest that relatively minor injuries are being admitted to these units. Analysis of smoke inhalation injuries showed admission to various different specialties. Admission to burn services ensures that key specialties are available for the care of complex burn injuries. These multidisciplinary teams include burn nurses, burn surgeons and burn anaesthetists/intensivists. From the data available, it was not possible to assess the appropriateness of admission of burns and smoke inhalation injuries to the various branches of medicine. In order to assess appropriateness, we need information on severity of injury and outcome of treatment in each specialty. Further research in this area is required since it is concerning that many burns/smoke inhalation injuries are being treated by specialties with no formal training in burn care medicine. This may have major implications for service planning alongside changes in referral patterns.

  6. Childhood leukaemia and ordnance factories in west Cumbria during the Second World War.

    PubMed

    Kinlen, L

    2006-07-01

    Much evidence has accumulated that childhood leukaemia (CL) is a rare response to a common, but unidentified, infection and in particular that situations involving the unusual mixing of urban and rural groups (approximating to, respectively, groups infected with, and susceptible to, the relevant microorganism) can produce localised epidemics with consequent increases of the infrequent leukaemic complication. During the Second World War, explosives production factories were built and operated at Drigg and Sellafield, and a shell filling factory at Bootle, in west Cumbria, England, requiring substantial numbers of construction workers to be brought into this remote and isolated area. Following the design of an earlier study of CL near large (post-war) rural construction sites, mortality from this disease was investigated with the help of the Office of National Statistics, in the area around these Cumbrian factories where local workers largely lived, during the construction period and with particular reference to the overlapping construction and operational phase when the mixing of local and migrant workers would have been greatest. An excess of leukaemia deaths at ages 1-14 was found during the construction period (observed 3; observed/expected (O/E) 2.2, 95% confidence interval (CI): 0.6, 6.0), which was more marked and statistically significant during the overlap with operations (O 3; O/E 4.5, 95% CI: 1.1, 12.2), especially at ages 1-4 (O 2; O/E 7.1, CI: 1.2, 23.6). A previous investigation did not detect this excess because it considered only a small part of west Cumbria that omitted the communities where most of the workforce lived, having incorrectly attributed the post-war expansion of the village of Seascale (situated between Drigg and Sellafield) to the wartime ordnance factories. The present findings are consistent with the results of the earlier study of rural construction projects and with the general evidence that marked rural-urban population mixing

  7. Trophic relay and prey switching - A stomach contents and calorimetric investigation of an ambassid fish and their saltmarsh prey

    Trophic relay is an ecological model that involves the movement of biomass and energy from vegetation, such as saltmarshes, within estuaries to the open sea via a series of predator-prey relationships. Any potential for trophic relay is therefore affected by water movements within an estuary and by the ability of a predator to "switch" prey in response to fluctuating abundances of those prey. Saltmarsh-dwelling grapsid crabs, which feed on saltmarsh-derived detritus and microphytobenthos, release zoeae into ebbing tides that inundate saltmarshes during spring-tide cycles within tidally-dominated estuaries, such as Brisbane Water Estuary, therefore providing an opportunity to examine whether prey-switching and/or trophic relay may occur in fish that feed on those zoeae (such as the highly abundant estuarine ambassid, Ambassis jacksoniensis). This model was examined by sampling A. jacksoniensis near saltmarshes in a large, temperate south-eastern Australian estuary during flood and ebb tides on days of saltmarsh inundation and non-inundation over four spring-tide events in 2012. Stomach fullnesses of A. jacksoniensis were generally highest during ebb tides on days of saltmarsh inundation, implying that feeding was most marked at these times. Caridean decapods dominated diets during flood tides and on days of no saltmarsh inundation, while crab zoeae dominated diets during ebb tides and on days of inundation, suggesting that, when saltmarsh-derived zoeae became abundant, A. jacksoniensis switched to feeding on those prey. Three potential zooplankton prey (calanoid copepods, caridean decapods and crab zoeae) did not differ calorimetrically, indicating that switching of prey by A. jacksoniensis is not directly related to their preying on energetically greater prey, but reflects opportunistic feeding on more abundant and/or less elusive prey. As A. jacksoniensis is able to switch prey from estuarine caridean decapods to saltmarsh-derived crab zoeae, this very abundant

    A three-year study of Connecticut, USA, salt-marsh vegetation was undertaken to determine the relationship of its distribution on the marsh surface to tidal levels, particularly mean high water (MHW) as measured on each of three sites representing different tidal amplitudes. Elevations and species present were measured on 1-m/sup 2/ grids in 10 x 70-m belt transects at each site. After the data were subjected to discriminant analysis and other standard statistical procedures, the results showed that 98.4% of all observations of Spartina alterniflora Loisel. occurred at or below MHW. The data can aid in salt-marsh restoration by offering a reliable indicator of what species should be planted when restored elevations and on-site MHW are known.

  9. Marsh Pool and Tidal Creek Morphodynamics: Dynamic Equilibrium of New England Saltmarshes?

    2012-12-01

    Under natural conditions, high saltmarsh platforms in New England exhibit poor drainage, creating waterlogged pannes (where short-form Spartina alterniflora dominates) and stagnant pools that experience tidal exchange only during spring tides and storm-induced flooding events. It is well accepted that a legacy of ditching practices (either for agriculture or mosquito control purposes) provide "overdrainage" of saltmarshes (after Redfield, 1972) and a shift in biogeochemical conditions: lowering of groundwater tables, aeration of soil, and decrease in preserved belowground biomass. Analysis of historical imagery in the Plum Island Estuary of Massachusetts reveals closure and decrease in length of anthropogenic ditches in recent decades is closely linked to marsh pool evolution. Field analyses including stratigraphic transects and elevation surveys suggest these marshes are reverting to natural drainage conditions. Further, an important dynamic interaction exists between saltmarsh pools and natural tidal creeks: creeks incise into pool areas, causing drainage of the pools, and formation of an unvegetated mudflat which can be rapidly recolonized by halophytic Spartina alterniflora vegetation. It was determined that pool and creek dynamics are cyclic in nature. The marsh platform is in dynamic equilibrium with respect to elevation and sea-level whereby marsh elevation may be lost (due to degradation of organic matter and formation of a pool) however may be regained (by creek incision into pools, restoration of tidal exchange, and rapid vertical accretion with Spartina alterniflora recolonization. Since vertical accretion in saltmarshes is a function of both organic and inorganic contributions to the marsh subsurface, it is hypothesized that cannibalization of existing muds is supplying inorganic material in this sediment starved system.

    How do salt-marsh ecosystems respond to changes in the environmental forcings? This is a question of paramount importance due to the critical role exerted by salt-marsh ecosystems within the tidal landscape. Salt marshes in fact buffer coastlines against, filter nutrients and pollutants from tidal waters, provide nursery areas for coastal biota, and serve as a sink for organic carbon. Observations of marsh degradation worldwide and the acceleration in the rate of global sea level rise highlight the importance of improving our understanding of the chief processes controlling salt-marsh response to current natural climate changes and to the effects of changes in sediment supply. To address this important issue, we have applied a analytical model of biomorphodynamic evolution of salt-marsh ecosystems in the vertical plane, accounting for two-way interactions between ecological and geomorphological processes. Our results show that marshes are more resilient to a step decrease in the rate of relative sea level rise (RRSLR) rather than to a step increase of the same magnitude. However, marshes respond more rapidly to an increase in sediment load or vegetation productivity, rather than to a decrease (of the same amount) in sediment load or vegetation productivity. We also observe that marsh stability is therefore positively correlated with tidal range: marshes with high tidal ranges respond more slowly to changes in the environmental forcings and therefore are less likely to be affected by perturbations. Finally, the model suggests that, in the case of a oscillating RRSLR, marsh stratigraphy will be unable to fully record short-term fluctuations in relative mean sea level, whereas it will be able to capture long-term fluctuations particularly in sediment rich, microtidal settings.

    Coastal saltmarsh and their constituent components and processes are of an interest scientifically due to their ecological function and services. However, heterogeneity and seasonal dynamic of the coastal wetland system makes it challenging to map saltmarshes with remotely sensed data. This study selected four important saltmarsh species Pragmitis australis, Sporobolus virginicus, Ficiona nodosa and Schoeloplectus sp. as well as a Mangrove and Pine tree species, Avecinia and Casuarina sp respectively. High Spatial Resolution Worldview-2 data and Coarse Spatial resolution Landsat 8 imagery were selected in this study. Among the selected vegetation types some patches ware fragmented and close to the spatial resolution of Worldview-2 data while and some patch were larger than the 30 meter resolution of Landsat 8 data. This study aims to test the effectiveness of different classifier for the imagery with various spatial and spectral resolutions. Three different classification algorithm, Maximum Likelihood Classifier (MLC), Support Vector Machine (SVM) and Artificial Neural Network (ANN) were tested and compared with their mapping accuracy of the results derived from both satellite imagery. For Worldview-2 data SVM was giving the higher overall accuracy (92.12%, kappa =0.90) followed by ANN (90.82%, Kappa 0.89) and MLC (90.55%, kappa = 0.88). For Landsat 8 data, MLC (82.04%) showed the highest classification accuracy comparing to SVM (77.31%) and ANN (75.23%). The producer accuracy of the classification results were also presented in the paper.

    Loss of coastal saltmarshes in southern California has been estimated at 75-90% since presettlement times. The remaining wetlands are mostly fragmented and degraded, and most frequently have harsh edges adjacent to urban landscapes. Non-migratory Belding's Savannah Sparrows (Passerculus sandwichensis beldingi) and Light-footed Clapper Rails (Rallus longirostris levipes) are endemic to saltmarshes in southern California and Baja California, Mexico. Population sizes of Belding's Savannah Sparrows show a positive relationship with saltmarsh area, but few large wetland fragments remain within their range in California. Belding's Savannah Sparrows are sensitive to fragmentation and isolation, with small isolated marshes acting as population sinks. In addition, this subspecies shows low genetic variability, limited dispersal, and small effective population sizes. Light-footed Clapper Rails are habitat specialists, found in marshes with good tidal flushing that support California cordgrass (Spartina foliosa) habitats. Light-footed Clapper rails also show low genetic variability and limited dispersal and the remnant populations of clapper rails are relatively isolated from one another. Large wetland complexes may serve as population sources for both species, while small, isolated marshes may act as population sinks but more research is needed to estimate and model the dynamics of these two metapopulations. Mitigation for wetland loss and restoration projects should not be evaluated simply by presence of rare bird species alone, but instead efforts should be made to determine population sustainability.

    During recent decades, over 40% of Japanese estuarine tidal flats have been lost due to coastal developments. Local populations of the saltmarsh sesarmid crab Clistocoeloma sinense, designated as an endangered species due to the limited suitable saltmarsh habitat available, have decreased accordingly, being now represented as small remnant populations. Several such populations in Tokyo Bay, have been recognised as representing distributional limits of the species. To clarify the genetic diversity and connectivity among local coastal populations of Japanese Clistocoeloma sinense, including those in Tokyo Bay, mitochondrial DNA analyses were conducted in the hope of providing fundamental information for future conservation studies and an understanding of metapopulation dynamics through larval dispersal among local populations. All of the populations sampled indicated low levels of genetic diversity, which may have resulted from recent population bottlenecks or founder events. However, the results also revealed clear genetic differentiation between two enclosed-water populations in Tokyo Bay and Ise-Mikawa Bay, suggesting the existence of a barrier to larval transport between these two water bodies. Since the maintenance of genetic connectivity is a requirement of local population stability, the preservation of extant habitats and restoration of saltmarshes along the coast of Japan may be the most effective measures for conservation of this endangered species.

    Terrestrial foodstuffs and other materials of agricultural importance have been analyzed for fission products and actinides discharged in waste from the Sellafield processing works in west Cumbria . Results obtained between 1977 and 1982 are summarized and it is concluded that the internal radiation exposure of the general public due to consumption of locally produced food in no instance amounts to more than a small fraction of recommended limits. Deposition of seaborne sediment is shown to be the main route by which radionuclides of Sellafield origin reach grazing land bordering a nearby tidal estuary.

    Salt-marsh foraminifera have been widely used as proxies to reconstruct sea-level trends because their modern distribution is strongly linked with tidal elevation, and they are relatively abundant and have a high preservation potential in intertidal sediments. To determine former sea levels, the relation between contemporary foraminifera and their controlling environmental variables must be determined and the influence of post-depositional changes elucidated. Duration and frequency of tidal exposure, while the dominant control, is not the only environmental variable controlling the distribution of foraminifera. Complex interactions between organisms and their environment factor into foraminifera species distributions and these factors will vary over space and time. Here we present preliminary results of a spatial and temporal ecological study to monitor short-term, seasonal, and interannual variations in salt-marsh foraminifera assemblages along a salinity gradient of an intertidal zone of New Jersey, USA. The temporal nature is beneficial in recording potential lags in response to changes in environmental conditions compared with one-time sampling. Live foraminifera assemblage samples are compared with measured environmental parameters (porewater chemistry, porewater nutrients, tidal inundation, grain size) and experiments (bioturbation, overwash deposit, and infaunal) to determine the controlling environmental variables on foraminifera and how these variables and the foraminifera assemblages change through time. Ultimately, this multi-year monitoring experiment provides a more comprehensive understanding of environmental controls on salt-marsh foraminifera and will provide a background data set of salt-marsh foraminifera to compare with future studies and with sampling after large events such as storms. A greater understanding of salt-marsh foraminifera in their environment will contribute to sea-level reconstructions. Since sea-level records use the distribution

  16. Microbial Manganese Oxidation in Saltmarsh Surface Sediments Using a Leuco Crystal Violet Manganese Oxide Detection Technique

    1994-01-01

    Microbial manganese (Mn) oxide production in surface sediments of a Georgia saltmarsh was directly measured using an assay involving the oxidation of 4,4',4″-methylidynetris (N,N-dimethylaniline), leuco crystal violet (LCV), by Mn oxides to produce crystal violet. The assay exhibits high specificity for Mn oxides without interference by Mn(II) and is sufficiently sensitive to determine rates of Mn oxidation in surface sediment or saltmarsh creek water suspensions. Sample salinity affects crystal violet absorbance in the 0-25 salinity range and must be corrected for in Mn oxide determinations for estuarine samples of variable salinity. Other oxidants found to oxidize LCV slowly included Cl(I), Cr(III), I(V), Fe(III), and Mn(III), although the sensitivity of the assay for Mn(IV) oxides was found to be seven times greater than for Mn(III), and at least 100 times greater than for any of the other oxidants. Rates of abiotic Mn oxide production in sediment suspensions treated with either sodium azide or formalin, or autoclaved, were much slower than rates determined for untreated sediments. Sodium azide (7·7 mM) inhibited Mn oxide production in these sediment suspensions to rates between 5 and 10% of the rates of Mn oxidation determined for unamended suspensions. Manganese oxidation was highly temperature dependent, with maximal rates on a dry weight basis (8·9 nmol mg dwt -1 h -1), occurring at 60°C, and negligible activity at 100 and 0°C. Rates were also dependent on sample pH, with maximal rates at pH 6·7, decreasing to near 0 as the pH was lowered to approximately 3·0. For Mn(II) concentrations ranging from 9 to 91 μM, rates of Mn oxide production were independent of Mn(II) concentration, while Mn oxide production was inhibited at concentrations greater than 91 μM (e.g. by 25-40% at 450 μM). Rates of microbial Mn oxide production in surface sediment/saltmarsh creek water suspensions incubated under natural conditions of temperature, pH, and Mn

The sparrow was assessed for feather mercury levels and the brain analyzed for cerebellar abnormalities by microscopic examination. In humans, fetal Minamata disease is caused by maternal ingestion of mercury. It is characterized by disrupted and disordered cerebellar neuronal migration in the fetus or infant. Results from this sparrow show cerebellar abnormalities typical of Minamata disease. It is the first known avian or mammalian specimen taken from the wild to show the abnormalities typical of the human fetal syndrome.

    2016-06-01

    Measurements of porewater O2, pH, and H2S microprofiles in intact sediment cores collected in a northern saltmarsh in the St. Lawrence Estuary (Quebec, Canada) revealed the occurrence of electrogenic sulfur oxidation (e-SOx) by filamentous "cable" bacteria in submerged marsh pond sediments in the high marsh. In summer, the geochemical fingerprint of e-SOx was apparent in intact cores, while in fall, cable bacteria were detected by fluorescence in situ hybridization and the characteristic geochemical signature of e-SOx was observed only upon prolonged incubation. In exposed, unvegetated creek bank sediments sampled in the low marsh in summer, cable bacteria developed only in repacked cores of sieved (500 μm), homogenized sediments. These results suggest that e-SOx is suppressed by the activity of macrofauna in exposed, unvegetated marsh sediments. A reduced abundance of benthic invertebrates may promote e-SOx development in marsh ponds, which are dominant features of subarctic saltmarshes as in the St. Lawrence Estuary. PMID:27104296

    Spartina alterniflora has widely invaded the saltmarshes of the Yangtze River Estuary and brought negative effects to the ecosystem. Remote sensing technique has recently been used to monitor its distribution, but the similar morphology and canopy structure among S. alterniflora and its neighbor species make it difficult even with high-resolution images. Nevertheless, these species have divergence on phenological stages throughout the year, which cause distinguishing spectral characteristics among them and provide opportunities for discrimination. The field spectra of the S. alterniflora community as well as its major victims, native Phragmites australis and Scirpus mariqueter, were measured in 2009 and 2010 at multi-phenological stages in the Yangtze River Estuary, aiming to find the most appropriate periods for mapping S. alterniflora. Collected spectral data were analyzed separately for every stage firstly by re-sampling reflectance curves into continued 5-nm-wide hyper-spectral bands and then by re-sampling into broad multi-spectral bands – the same as the band ranges of the TM sensor, as well as calculating commonly used vegetation indices. The results showed that differences among saltmarsh communities’ spectral characteristics were affected by their phenological stages. The germination and early vegetative growth stage and the flowering stage were probably the best timings to identify S. alterniflora. Vegetation indices like NDVI, ANVI, VNVI, and RVI are likely to enhance spectral separability and also make it possible to discriminate S. alterniflora at its withering stage. PMID:23826265

    We describe the modern distribution of salt-marsh and tidal-flat foraminifera from Sitkinak Island (Trinity Islands) and Simeonof Island (Shumagin Islands), Alaska, to begin development of a dataset for later use in reconstructing relative sea-level changes caused by great earthquakes along the Alaska-Aleutian subduction zone. Dead foraminifera were enumerated from a total of 58 surface-sediment samples collected along three intertidal transects around a coastal lagoon on Sitkinak Island and two intertidal transects on Simeonof Island. Two distinctive assemblages of salt-marsh foraminifera were recognized on Sitkinak Island. Miliammina fusca dominated low-marsh settings and Balticammina pseudomacrescens dominated the high marsh. These two species make up >98% of individuals. On Simeonof Island, 93% of individuals in high-marsh settings above mean high water were B. pseudomacrescens. The tidal flat on Simeonof Island was dominated by Cibicides lobatulus (60% of individuals), but the lower limit of this species is subtidal and was not sampled. These results indicate that uplift or subsidence caused by repeated earthquakes along the Alaska-Aleutian subduction zone could be reconstructed in coastal sediments using alternating assemblages of near monospecific B. pseudomacrescens and low-marsh or tidal-flat foraminifera.

    2000-11-01

    Concentrations of Fe, Mn, Ni, Cu, Cr and Zn in their total, silicate, organic, reactive and pyrite fractions were determined in soils collected from the Ortigueira saltmarshes (Esteiro, Ladrido and Mera, NW Iberian Peninsula), from sediments of the Landoi and Esteiro Rivers, and from sludge generated by a nearby dunite mine. The Esteiro saltmarsh presented clear enrichments of the four metals studied (first 10 cm), especially of Ni and Cr, whose concentrations were among the highest. It is proposed that the elevated Cr and Ni levels found in the Esteiro saltmarsh were derived from recent contributions of the mine, which are partially discharged into the Landoi River. Total Cu and Zn concentrations were lower than the corresponding ones for Cr and Ni. Under suboxic conditions, Ni, Cr, Cu and Zn were mainly associated with the reactive fraction. Under anoxic conditions, Cu and Ni were associated mainly with the pyrite phase. Pyritic Zn and Cr concentrations were relatively low and similar in all three saltmarshes; however, where anoxic-sulfidic conditions prevailed these two metals were mainly associated with the reactive and organic fractions.

    The distributions of 134Cs, 137Cs and 106Ru in intertidal surface sediments from the coasts of Cumbria and Lancashire, north-west England, are reported. The ratios of 134Cs: 137Cs and 106Ru: 137Cs activities have been used together with the isotopic composition of the Windscale radioactive effluents to examine the contamination history of sediments. Distinct differences between the activities and time of contamination of muds, silts and sands are found, and the apparent lag times of transport of radioactive wastes to different sediment localities are estimated. The relatively high activities in fine sediments reflect recent discharges indicating a rapid response to discharge, while the sands contain low levels of older contamination. Apparent lag times of up to 6 years are estimated for the study area; the transport to the south is generally more rapid than to the north. These results have consequences for the operation and interpretation of radiological monitoring in coastal areas.

    The ongoing Late Holocene sea-level rise has inundated a series of low (< 2m above sea level) relict sand ridges on Cedar Island, in southern Pamlico Sound on the central North Carolina coast (35.00°N, 76.34°W). The ridges likely represent shorelines formed during a previous (Pleistocene) sea-level highstand by a combination of longshore transport and eolian dune processes. Saltmarsh peat comprising primarily the remains of the high marsh plant Juncus gerardii has accumulated between the ridges, yielding a continuous record of transgression over at least the last 2,000 years. The protected depositional setting between the ridges, the small tidal amplitude (< 25 cm) in southern Pamlico Sound, and the smoothly varying topography of the underlying sand surface provide the opportunity to acquire basal saltmarsh peat samples from a range of elevations for sea-level reconstruction. We obtained cores of the marsh peat and sand deposits using various techniques (hand auger, Russian and dutch peat corers, vibracore) to generate an overview of the stratigraphy in the study area. We visually logged the cores and analyzed samples for organic carbon content, particle size and magnetic susceptibility. In the marsh peat, plant macrofossils were identified and agglutinated foraminiferal assemblages were counted. Saltmarsh foraminifera species identified in the cores include Trochammina inflata, Ammoastuta inepta, Jadammina macrescens, Tiphotroca comprimata and Milliamina fusca. Radiocarbon dates on plant material provide chronological control. Marsh core elevations were referenced to NAVD88 by total station surveys to the NGS benchmark on Cedar Island. We have acquired marsh cores as deep as 3.25 m below local mean sea level (MSL), but thus far the deepest saltmarsh peat sample found to contain saltmarsh foraminifera is from 2.16 m below MSL. The marsh deposits are laterally consistent in the upper 1.5 m of core transects, but minor downcore variations in organic content

    STUDY OBJECTIVE: To investigate whether the occupational exposure to external ionising radiation of men employed at the Sellafield nuclear installation, West Cumbria, affects the sex of the children they subsequently father. DESIGN: A retrospective cohort study using logistic regression to analyse the sex ratio, in particular in relation to paternal preconceptional irradiation. SETTING AND PARTICIPANTS: The 260,060 singleton births between 1950 and 1989 to mothers resident in Cumbria, north west England. RESULTS: The sex ratio among children of men employed at any time at Sellafield was 1.094 (95% CI: 1.060, 1.128), significantly higher than that among other Cumbrian children, 1.055 (95% CI: 1.046, 1.063). There was an increased sex ratio of 1.396 (95% CI: 1.127, 1.729) in the 345 children whose fathers were estimated from annual dose summaries to have received more than 10 mSv of external radiation in the 90 days preceding conception, but no significant linear trend between sex ratio and 90 day paternal preconceptional dose was found. There was no significant association between sex ratio and the external dose accumulated before the 90 day period preceding conception. CONCLUSIONS: Men employed at Sellafield fathered a greater proportion of boys than would be expected for a Cumbrian population, which may be partly explained by their younger age distribution. A greater effect was observed in the fathers with recorded doses exceeding 10 mSv in the 90 days before conception. While this may reflect a true statistical association, it is also possible that it may be a chance finding due to imprecision in the dose estimates and consequent misclassification. PMID:9039384

    Nearly all saltmarshes in east-central, Florida were impounded for mosquito control during the 1960s. The majority of these marshes have since been reconnected to the estuary by culverts, providing an opportunity to effectively measure exchange of aquatic organisms. A multi-gear approach was used monthly to simultaneously estimate fish standing stock (cast net), fish exchange with the estuary (culvert traps), and piscivore abundance (gill nets and bird counts) to document patterns of fish use in a reconnected saltmarsh impoundment. Changes in saltmarsh fish abundance, and exchange of fish with the estuary reflected the seasonal pattern of marsh flooding in the northern Indian River Lagoon system. During a 6-month period of marsh flooding, resident fish had continuous access to the marsh surface. Large piscivorous fish regularly entered the impoundment via creeks and ditches to prey upon small resident fish, and piscivorous birds aggregated following major fish movements to the marsh surface or to deep habitats. As water levels receded in winter, saltmarsh fish concentrated into deep habitats and emigration to the estuary ensued (200% greater biomass left the impoundment than entered). Fish abundance and community structure along the estuary shoreline (although fringed with marsh vegetation) were not analogous to marsh creeks and ditches. Perimeter ditches provided deep-water habitat for large estuarine predators, and shallow creeks served as an alternative habitat for resident fish when the marsh surface was dry. Use of the impoundment as nursery by transients was limited to Mugil cephalus Linnaeus, but large juvenile and adult piscivorous fish used the impoundment for feeding. In conclusion, the saltmarsh impoundment was a feeding site for piscivorous fish and birds, and functioned as a net exporter of forage fish to adjacent estuarine waters. ?? Springer 2006.

    How do interacting physical and biological processes control the form and evolution of salt-marsh landscapes? Salt marshes are shaped by the erosion, transport and deposition of sediment, all of which are mediated by vegetation. In addition, vegetation plays a key role in deposition of organic material within marsh sediments. The influence of biota on salt-marsh landscapes is indeed well established. However, a fascinating and relevant question is whether one can identify the signatures of the underlying and intertwined physical and biological processes in marsh landscapes, and indeed infer from them the dynamic behavior of these coupled physical and biological systems. Can one detect landscape features that would not have emerged in the absence of interactions and feedbacks between physical and biological processes? Here we use field evidence and a two-dimensional biomorphodynamic model to show that the interplay between physical and biological processes generates striking biological and morphological patterns. One such pattern, vegetation zonation, consists of a mosaic of vegetation patches, of approximately uniform composition, displaying sharp transitions in the presence of extremely small topographic gradients. The model describes the mutual interaction and adjustment between tidal flows, sediment transport, morphology, and vegetation distribution, thus allowing us to study the biomorphodynamic evolution of salt-marsh platforms. A number of different scenarios were modelled to analyze the changes induced in bio-geomorphic patterns by varying environmental forcings, such as the rate of relative sea level rise (RSLR) andsediment supply (SS), and by plant species with different characteristics. Model results show how marsh responses to changes in forcings are highly spatially dependent: while changes in SS most directly affect marsh areas closest to the channels, changes in the rate of RSLR affect the marsh platform as a whole.

    A sediment disk reactor was tested in once flow-through mode to retrieve kinetic parameters for the Monod rate law that describes sulfate reduction. The experimental method was compared with a previously described procedure by the authors where a sediment plug-flow reactor was operated in a recirculation mode. In recirculation mode, accumulation of metabolic byproducts in certain cases may result in negative feedback, thus preventing accurate determination of kinetic information. The method described in this article provides an alternative to the recirculation sediment plug-flow-through reactor technique for retrieving kinetic parameters of microbially mediated reactions in aquatic sediments. For sulfate reduction in a saltmarsh site, a maximum estimate of the half-saturation concentration, Ks, of 204±26 μM and a maximum reaction rate, Rm, of 2846±129 nmol cm( wet sediment ) 3 d-1 was determined. The Ks value obtained was consistent with the one estimated previously (K s=240±20 μM) from a different site within the same saltmarsh mud flat using a recirculating reactor. From the Rm value and reduction rates determined using 35SO 42- incubation experiments, we infer that sulfate reduction is limited in the field. Substrate availability is not the main contributor for the limitation, however. Competition from other microbes, such as iron reducers affects the activity of sulfate reducers in the suboxic to anoxic zones, whereas aerobes compete in the oxic zone. High sulfide concentration in the pore water may also have acted as a toxin to the sulfate reducers in the field.

  8. Characterization of Mercury and Its Risk in Nelson’s, Saltmarsh, and Seaside Sparrows

    Background Nelson’s, Saltmarsh, and Seaside Sparrows (Ammodramus nelsoni, A. caudacutus, and A. maritimus, respectively) depend on marsh and wetland habitats – ecosystems in which mercury (Hg) bioavailability is notoriously high. The purpose of the present study was to address the potential impact of Hg on these species using first primary and breast feathers as non-destructive biomonitoring tools. Methods and Principal Findings Feathers were sampled from wintering sparrows in North Carolina salt marshes (2006–2010). Feather Hg data were used in three risk analysis components (1) Threshold Component – examined feather Hg with regard to published negative effects thresholds; (2) Hg Dynamics Component – examined Hg in sparrows captured multiple times; and (3) Capture Frequency and Survival Component – tested for links between Hg and return frequency and survival. Threshold Component analyses indicated that Hg concentrations in 42–77% of sampled individuals (breast feather n = 879; first primary feather n = 663) were within the range associated with decreased reproduction in other avian species. Hg Dynamics Component analyses demonstrated that Hg increased between first and second captures for Nelson’s (n = 9) and Seaside Sparrows (n = 23). Capture Frequency and Survival Component analyses detected a negative relationship between Hg and capture frequency in Nelson’s Sparrows (n = 315). However, MARK models detected no effect of Hg on apparent survival in any species. Conclusion and Significance This study indicates that current Hg exposure places a considerable proportion of each population at risk. In particular, 52% of all sampled Saltmarsh Sparrows exhibited first primary feather Hg concentrations exceeding those associated with a >60% reduction in reproductive success in other species. This study reports evidence for net annual bioaccumulation, indicating an increased risk in older individuals. These data can be used to inform

    The present work studied the effect of extracts from tissue culture-derived callus and leaf of the saltmarsh plant, Sesuvium portulacastrum L. on synthesis of antimicrobial silver nanoparticles using AgNO(3) as a substrate. The callus extract could be able to produce silver nanoparticles, better than leaf extract. The synthesis of silver nanoparticles was confirmed with X-ray diffraction spectrum which exhibited intense peaks, corresponding to the (1 1 1), (2 0 0), (2 2 0), (3 1 1), and (2 2 2) sets of lattice planes of silver. The extracts incubated with AgNO(3) showed gradual change in color of the extracts to yellowish brown, with intensity increasing during the period of incubation. Control without silver nitrate did not show any change in color. The silver nanoparticles synthesized were generally found to be spherical in shape with variable size ranging from 5 to 20 nm, as evident by Transmission Electron Microscopy. There were prominent peaks in the extracts corresponding to amide I, II and III indicating the presence of the protein, as revealed by Fourier transform infrared (FTIR) spectroscopy measurement. There were also peaks that were corresponding to aromatic rings, geminal methyls and ether linkages, indicating the presence of flavones and terpenoids responsible for the stabilization of the silver nanoparticles. The silver nanoparticles were observed to inhibit clinical strains of bacteria and fungi. The antibacterial activity was more distinct than antifungal activity. The antimicrobial activity was enhanced when polyvinyl alcohol was added as a stabilizing agent. The present work highlighted the possibility of using tissue culture-derived callus extract from the coastal saltmarsh species for the synthesis of antimicrobial silver nanoparticles.

    Intertidal wetlands such as saltmarshes and mangroves provide numerous important ecological functions, though they are in rapid and global decline. To better conserve and restore these wetland ecosystems, we need an understanding of the fundamental natural bottlenecks and thresholds to their establishment and long-term ecological maintenance. Despite inhabiting similar intertidal positions, the biological traits of these systems differ markedly in structure, phenology, life history, phylogeny and dispersal, suggesting large differences in biophysical interactions. By providing the first systematic comparison between saltmarshes and mangroves, we unravel how the interplay between species-specific life-history traits, biophysical interactions and biogeomorphological feedback processes determine where, when and what wetland can establish, the thresholds to long-term ecosystem stability, and constraints to genetic connectivity between intertidal wetland populations at the landscape level. To understand these process interactions, research into the constraints to wetland development, and biological adaptations to overcome these critical bottlenecks and thresholds requires a truly interdisciplinary approach.

    Motor neurone disease (MND) is a fatal neurodegenerative disease of unknown aetiology. Malnutrition is a common occurrence and an independent risk factor for worse prognosis. However, it remains unclear whether provision of enteral nutrition (EN) through a gastrostomy tube offers any survival advantage. Our aim was to describe the demographic and clinical characteristics of MND in Lancashire and South Cumbria in North West England and the impact of EN on survival in the 8 year period of 2005-2012. Four hundred and seven patients with MND were identified through the Preston MND care and research centre registry giving a crude incidence rate of 3.15/100,000. Three hundred and forty patients with adequate information were included in the final analysis of whom 53.2% were male. The presentation was limb/spinal in 62.1% and bulbar in 37.9% of patients, bulbar onset being more common in elderly females. Mean age of onset was 67.28 years (standard deviation 11.06; range 22.78-93.06). Median survival was 1.98 years (range 1.18-3.05). Ninety-one patients received EN of whom 67% had bulbar onset disease. EN was not associated with a statistically significant survival advantage except for the subgroup who received EN more than 500 days after symptom onset. In conclusion, the early requirement for EN may indicate a prognostically less favourable subgroup.

    This paper summarizes sedimentological and hydrological studies at a salt marsh site on the north bank of the River Esk near Ravenglass which have a bearing on the fate of the low-level radioactive effluent from the reprocessing facility at Sellafield, Cumbria. A range of techniques has been used including electromagnetic distance measurement (EDM) and pore water pressure studies. The results show that: (a) Over a two-year period there were no significant net changes in salt marsh creek level, although shorter-term (probably seasonal) fluctuations, of the order of 2 cm, occurred. These were attributed to expansion of clay particles during the winter months. Nearby, however, there were vertical changes of the order of 1 m due to erosion. (b) Pore water pressures indicated a dynamic situation with very rapid responses both to tidal fluctuations and to rainfall. During neap tides there was clear evidence for water seeping upwards from the underlying clay/sand interface. Shortlived radionuclides ( 95Zr/95Nb and 106Ru) were detected in this zone. (c) Soil polygons, once initiated by desiccation, thereafter provide preferential routes for water (and radionuclides) to the sub-surface sediment. These, and other results, are discussed in the context of previous studies. It is concluded that the complexity of the estuarine environment results in most data being site specific.

    In March 1999, a large community outbreak of Escherichia coli O157 infection occurred in North Cumbria. A total of 114 individuals were reported to the Outbreak Control Team (OCT); 88 had laboratory confirmed E. coli O157. Twenty-eight (32%) of the confirmed cases were admitted to hospital, including three children (3.4%) with haemolytic uraemic syndrome. There were no deaths. A case-control study found that illness was strongly associated with drinking pasteurized milk from a local farm (P = <0.0001) on single variable analysis. Microbiological investigations at the farm revealed E. coli O157 phage type (PT) 21/28 VT 2 which was indistinguishable from the human isolates by pulsed field gel electrophoresis. At the time of occurrence this was the largest E. coli O157 outbreak in England and Wales and the first E. coli O157 PT 21/28 VT 2 outbreak associated with pasteurized milk. This outbreak highlights lessons to be learnt regarding on-farm pasteurization.

    We are assessing variability in mercury species in porewater, groundwater, and surface water at Sage Lot saltmarsh along the south shore of Cape Cod, MA. This relatively undisturbed coastal marsh is part of the Waquoit Bay National Estuarine Reserve and is surrounded by undeveloped wooded uplands. The marsh substrate is comprised of an organic-rich peat layer that reaches a maximum thickness of ~2 m at the water's edge and overlays the regional sand groundwater aquifer. We collected porewater depth profiles within the peat layer along an approximately 120 m transect perpendicular to the shoreline (see figure). Total mercury (HgT) concentrations in porewater ranged from 2 to 6 pM in filtered (< 0.2 µm) water and from 10 to 20 pM in unfiltered water. Mercury concentrations in groundwater collected from a well installed about 20 m upgradient from the marsh were an order of magnitude higher (~ 130 pM and 170 pM in filtered and unfiltered water, respectively). Although ~70% of this mercury occurred in the presumably mobile (< 0.2 μm) fraction, the elevated groundwater concentrations did not appear to enhance HgT within the peat layer. Groundwater in sand immediately below the sand-peat interface, however, typically had HgT concentrations similar to those observed in peat, suggesting porewater infiltration to the underlying aquifer. We also collected time series surface water samples over tidal flooding and draining cycles. Filtered and unfiltered surface water HgT were similar to concentrations observed in peat porewater and did not change in response to the tidal cycle. Preliminary data suggests methylmercury (MeHg) in filtered porewater was about 1 pM (i.e., ~20% MeHg), indicating enhanced mercury methylation within the anoxic peat layer. If the similarity between peat porewater and marsh surface water HgT concentrations is a result of hydraulic exchange between the porewater and offshore water, the saltmarsh may be an important source of bioavailable mercury to the

    A multi-proxy approach based on benthic foraminifera, sand content, short-lived radioisotope activities, heavy metal concentrations and aerial photography was developed to characterise the process of human disturbance on the intensely impacted eastern Cantabrian coast (N. Spain) over the last two centuries. Analysis of two 50 cm long sediment cores from different saltmarshes in the Santoña estuary and their comparison with previous results in nearby coastal areas defines criteria to identify records of agricultural activities in salt-marsh sediments. Agricultural occupation of saltmarshes and the later regeneration was recognised based on foraminifera and sand content. Saltmarshes in the eastern Cantabrian coast are expected to adapt to ongoing sea-level rise based on the high sedimentation rates (14-18 mm yr-1) observed during the regeneration process of previously reclaimed areas. These findings can potentially be useful in other temperate saltmarshes with abundant sediment input, as a cost-effective adaptation measure to counteract the effects of sea-level rise.

  16. Role of salt-marsh erosion in barrier island evolution and deterioration in coastal Louisiana

    Barrier shoreline erosion in Louisiana reaches over 10 m/year, and island area decreased by 40% between 1880 and 1979. Salt-marsh erosion is an important factor in evolutionary barrier shoreline development and is presently contributing, both directly and indirectly, to the deterioration of Louisiana's barrier islands. The marshes originally developed as fresh marshes associated with regression of Mississippi River delta lobes. After abandonment, salinity gradually increased and natural habitat change occurred as subsidence of deltaic sediments and transgression of the coastline by marine processes proceeded. The marsh surface is subjected to relative sea level rise and unless there is sufficient sedimentation to maintain marsh elevation, erosional processes become dominant. Increased inundation of marsh vegetation stresses even halophytic vegetation and leads to plant death. Examination of variations in marsh topography over an area of approximately 1 ha. revealed marked variations in the frequency and duration of tidal inundation. Increased flooding of lower areas can be sufficient to cause plant death and the opening of marsh ponds. As small ponds expand and coalesce to form larger areas of open water, wave action becomes important in eroding pond banks and mobilizing sediment from the bed causing pond deepening. Fragmentation of the marsh by these subsidence-induced processes is part of the evolution of morphostratigraphic forms in the Mississippi deltaic plain from erosional headland with flanking barriers to barrier island arc.

  17. Patterns in salt-marsh ecosystems: the role of biotic and abiotic forcings

    2010-12-01

    The dynamics of salt-marsh ecosystems are governed by interacting physical and biological processes, whose intertwined feedbacks critically affect the evolution. Salt marshes are characterised by complex patterns, both in their geomorphic and biological features, arising through the elaboration of a network structure driven by the tidal forcing and through the interaction between hydrodynamical, geophysical, and biological components. The complexity observed in tidal geomorphological patterns is deemed to arise from the mutual influence of biotic and abiotic components. The results from a 2D numerical model, accounting for biotic and geomorphic processes, show that the average marsh elevation within the tidal frame decreases with increasing rates of sea-level rise, decreasing sediment availability, and decreasing vegetation productivity. The spatial variability in platform elevations and biomass distribution, increases with increasing rates of sea-level rise, increasing sediment availability, and decreasing vegetation productivity. Supply-limited settings tend to develop uniform marsh surface elevations and biomass distribution, whereas supply-rich settings tend to develop sedimentation patterns characterized by large heterogeneities. Our analyses also suggest that the fate of tidal landforms and their possible geomorphological restoration should be addressed through approaches which explicitly incorporate bio-morphodynamic processes.

    Overexploitation of predators has been linked to the collapse of a growing number of shallow-water marine ecosystems. However, salt-marsh ecosystems are often viewed and managed as systems controlled by physical processes, despite recent evidence for herbivore-driven die-off of marsh vegetation. Here we use field observations, experiments, and historical records at 14 sites to examine whether the recently reported die-off of northwestern Atlantic salt marshes is associated with the cascading effects of predator dynamics and intensive recreational fishing activity. We found that the localized depletion of top predators at sites accessible to recreational anglers has triggered the proliferation of herbivorous crabs, which in turn results in runaway consumption of marsh vegetation. This suggests that overfishing may be a general mechanism underlying the consumer-driven die-off of salt marshes spreading throughout the western Atlantic. Our findings support the emerging realization that consumers play a dominant role in regulating marine plant communities and can lead to ecosystem collapse when their impacts are amplified by human activities, including recreational fishing.

In contrast, phosphorus and suspended sediment are positively associated with discharge (strongest relationship R2 = 0.94 for reactive P and R2 = 0.97 for total P were both recorded in spring campaign at Temple Sowerby gauging station; R2 = 0.87 was recorded in autumn seasonal campaign near Great Corby gauging station). Similarly the dryness or wetness of a season affects the nutrient concentrations. Thus, it appears that hydrology and land use distribution, from the headwater to the lowland areas downstream, control the spatial behaviour of the nutrient and suspended sediment concentration in the River Eden.

    We present a quantitative technique to reconstruct sea level from assemblages of salt-marsh foraminifera using partitioning around medoids (PAM) and linear discriminant functions (LDF). The modern distribution of foraminifera was described from 62 surface samples at three salt marshes in southern New Jersey. PAM objectively estimated the number and composition of assemblages present at each site and showed that foraminifera adhered to the concept of elevation-dependent ecological zones, making them appropriate sea-level indicators. Application of PAM to a combined dataset identified five distinctive biozones occupying defined elevation ranges, which were similar to those identified elsewhere on the U.S. mid-Atlantic coast. Biozone A had high abundances of Jadammina macrescens and Trochammina inflata; biozone B was dominated by Miliammina fusca; biozone C was associated with Arenoparrella mexicana; biozone D was dominated by Tiphotrocha comprimata and biozone E was dominated by Haplophragmoides manilaensis. Foraminiferal assemblages from transitional and high salt-marsh environments occupied the narrowest elevational range and are the most precise sea-level indicators. Recognition of biozones in sequences of salt-marsh sediment using LDFs provides a probabilistic means to reconstruct sea level. We collected a core to investigate the practical application of this approach. LDFs indicated the faunal origin of 38 core samples and in cross-validation tests were accurate in 54 of 56 cases. We compared reconstructions from LDFs and a transfer function. The transfer function provides smaller error terms and can reconstruct smaller RSL changes, but LDFs are well suited to RSL reconstructions focused on larger changes and using varied assemblages. Agreement between these techniques suggests that the approach we describe can be used as an independent means to reconstruct sea level or, importantly, to check the ecological plausibility of results from other techniques.

    Saltmarsh is one of the important communities of wetlands. Due to a range of pressures, it has been declared as an EEC (Ecological Endangered Community) in Australia. In order to correctly identify different saltmarsh species, development of distinct spectral characteristics is essential to monitor this EEC. This research was conducted to classify saltmarsh species based on spectral characteristics in the VNIR wavelength of Hyperion Hyperspectral and Worldview 2 multispectral remote sensing data. Signal Noise Ratio (SNR) and Principal Component Analysis (PCA) were applied in Hyperion data to test data quality and to reduce data dimensionality respectively. FLAASH atmospheric correction was done to get surface reflectance data. Based on spectral and spatial information a supervised classification followed by Mapping Accuracy (%) was used to assess the classification result. SNR of Hyperion data was varied according to season and wavelength and it was higher for all land cover in VNIR wavelength. There was a significant difference between radiance and reflectance spectra. It was found that atmospheric correction improves the spectral information. Based on the PCA of 56 VNIR band of Hyperion, it was possible to segregate 16 bands that contain 99.83 % variability. Based on reference 16 bands were compared with 8 bands of Worldview 2 for classification accuracy. Overall Accuracy (OA) % for Worldview 2 was increased from 72 to 79 while for Hyperion, it was increased from 70.47 to 71.66 when bands were added orderly. Considering the significance test with z values and kappa statistics at 95% confidence level, Worldview 2 classification accuracy was higher than Hyperion data.

    Control and eradication of the exotic and invasive plant Spartina alterniflora within the Chongming Dongtan nature reserve, Shanghai, China, is vital for the management and conservation of the saltmarshes. A demonstration project was established using waterlogging and cutting to control this invasive species. Results from 2007 to 2008 showed that, although the managed waterlogging significantly reduced biomass and seed production of S. alterniflora at an early stage, the species subsequently showed rapid adaptation to the long-term waterlogging stress. Thus, managed waterlogging alone was insufficient for the effective eradication of S. alterniflora. However, managed waterlogging for around 3 months, combined with cutting the above-ground part of S. alterniflora at a key stage (flowering period in July), controlled and eradicated the plant successfully. Both the above-ground and below-ground parts of S. alterniflora were killed and the plants began to decompose after 3 months. Furthermore, there was no re-growth of the emergent part of S. alterniflora in the following years. However, once the impounded water was released restoring the natural hydrodynamic regime of the saltmarshes, the seeds and seedlings of S. alterniflora reinvaded the controlled site from the neighboring areas and the S. alterniflora community was re-established. Thus, after eradication of S. alterniflora, control measures should be maintained to prevent the re-establishment of S. alterniflora. The results of this demonstration project indicate a potentially useful and effective approach for the control and management of large-scale invasion by S. alterniflora on saltmarshes in the Yangtze Estuary, China.

    Over the last 15 years, rapid invasion of large areas of the saltmarshes of Chongming Island, in the Yangtze Estuary, China by the exotic species Spartina alterniflora has occurred. Two types of advancing fronts are found: the S. alterniflora-mudflat (S-M front) and the S. alterniflora - Scirpus mariqueter - mudflat (S-S-M front). In this study, both the range expansion in terms of seedling recruitment and tussock development at these two advancing fronts and the accretion/erosion dynamics used as a proxy for comparable hydrodynamic regimes were investigated. The results showed that the mean number of seedlings of S. alterniflora recruited at the S-M front was much higher than that at the S-S-M front. The rate of range expansion after one growing season at the S-M front was much faster than the S-S-M front. The different colonisation behaviours on the two types of advancing front was related to the differences in hydrodynamic regimes. At the site with a regime of autumn/winter erosion and spring/summer accretion, the original pioneer species of S. mariqueter was replaced by S. alterniflora and a pattern of range expansion at the S-M front developed. In contrast, at the site with a relatively stable accretion regime, the original pioneer species of S. mariqueter remained within the advancing front and a pattern of range expansion at the S-S-M front developed. The impact of abiotic and biotic factors governing the range expansion of S. alterniflora and its implications on the spatial structure of tidal wetlands is discussed.

    The estimated magnitude of the organic carbon (OC) stocks contained in the first meter of US coastal wetland soils represents ~10% of the entire OC stock in US soils (4 vs. 52 Pg, respectively). Because this stock extends to several meters below the surface for many coastal wetlands, it becomes paramount to understand the fate of OC under ecosystem shifts, varying natural environmental constraints, and changing land use. In this project we analyze the major classes of biochemicals including total hydrolysable neutral carbohydrates, enantiomeric amino acids, phenols, and cutins/suberins at two study sites located on the Texas coastline to investigate chemical composition and its controls on organic carbon preservation in mangrove (Avicennia germinans) and saltmarsh grass (Spartina alterniflora) dominated wetlands. Results show neutral carbohydrates and lignin contribute 30-70% and 10-40% of total OC, respectively, in plant litter and surface sediments at both sites. Sharp declines of carbohydrate yields with depth occur parallel to increasing Ac/AlS,V ratios indicating substantial decomposition of both the polysaccharide and lignin components of litter detritus. Contrasts in the compositions and relative abundances of all previously mentioned compound classes are further discussed to examine the role of litter biochemistry in OC preservation. For example, the selective preservation of cellulose over hemicellulose in sediments indicates macromolecular structure plays a key role in preservation between plant types. It is concluded that the chemical composition of litter material controls the composition and magnitude of OC stored in sediments. Ultimately, as these ecosystems transition from one dominant plant type to another, as is currently observed along the Texas coastline, there is the potential for OC sequestration efficiency to shift due to the changing composition of OC input to sediments.

    At the insistence of the local fishermen and landowners the Isle of Palms connector (Charleston, South Carolina) was built with a unique set of environmental safeguards so that the saltmarsh beneath the bridge would remain uncontaminated. This study evaluates the effectiveness of the bridge, in order to judge the suitability of the design for other areas. A two kilometer causeway over the marsh has catch pans to hold runoff, except that a heavy rain causes the pans to overflow. A one kilometer span over the Intracoastal waterway has pipes that redirect the runoff into gravel lined spoils. The bridge was monitored quarterly from January to December 1994. Extensive testing was performed during October 1994 to compare sites around the bridge and within the watershed to a pristine site and a to highly contaminated site. Sediment and water samples were tested with the Microtox{reg_sign} bioluminescence assay and a Latuca sativa (lettuce) seed germination and growth assay. Sediment samples were also tested with a Mercenaria mercenaria (littleneck clam) growth bioassay. Benthic community structure was analyzed for sites around the bridge. While very few statistically significant instances of toxicity were found, there are some trends that make it apparent that the bridge runoff may have some effects. There is no apparent accumulation of toxic contaminants from the pan overflow in sediments beneath the bridge, and this bridge design should ameliorate the effects of bridge runoff in almost any area. Future research using chemical analysis of the fate and transport of contaminants within the bridge and the surrounding area is suggested.

    Historical transformations of the saltmarshes in the six sub-basins of the Marano and Grado Lagoon were analyzed using aerial photographs (1954, 1990, 2006), and the support of historical maps and topographic surveys. Analysis of the 2006 set of aerial photographs enabled the definition of the present extent and distribution of the saltmarshes inside the lagoon (760 ha), with a total reduction in saltmarsh area of 16% (144 ha) compared to 1954. Direct human actions played a significant role in the budget, since total loss due to land reclamation and dredging during this period amounted to 126 ha. After excluding the total loss due to direct human interventions, different erosional and depositional marsh types were recognized and associated with different forcing factors, based on morphological and geographical evidence. Over the 52-year period marshes were lost due to: (a) drowning - the combined effects of eustatism, regional subsidence and autocompaction (102 ha); (b) edge-retreat by wind wave attack (34 ha); (c) erosion by vessel-generated waves (37 ha); and (d) coastal dynamics and inlet migration (5.7 ha). Conversely, marshes gained in area due to: (a) fluvial input (63 ha); (b) tidal input (27 ha); (c) paralagoonal deposition (45 ha); (d) the re-opening of abandoned fish farms (18 ha); and (e) the dumping of dredged material (8 ha). Our analysis demonstrates that local and short-term forcing factors can obliterate or compensate the long-term ones, especially the relative sea-level rise. A test of the integrated sediment budget carried out on one third of the total lagoon, through a bathymetric comparison between datasets from 1964 to 2009, pointed out that conservation or slight expansion of the marshes inside these basins were linked to an overall positive sediment budget of 61,000 m3/y. Nevertheless, significant morphological changes occurred in the submerged basin, which is affected by sustained deposition along the inner margins due to sediment supplies

    The saltmarsh cordgrass (Spartina alterniflora) is the dominant vascular plant in tidal marshes along the east and gulf coasts in the United States. This plant's ability to survive in polluted estuaries has led many researchers to investigate its role in heavy metal uptake and export. Spartina seeds accumulate a variety of metals as well, although seed concentrations are generally lower than those found in leaf tissue. It has been demonstrated that some heavy metals affect germination in this plant (e.g. methyl Hg, Zn, and Pb), while others, such as Cu and Cd, in solution concentrations as high as 100 mg/L, do not affect the germination response. Despite this, S. alterniflora seedlings grown in Cu solution exhibit 100 percent mortality within 56 d.

    Estuaries and coastal lagoons play a key role in the functioning of coastal ecosystems and represent important natural areas for fish communities. Species living in these habitats often show specialised ecological and life history traits. The reproductive periodicity of a northern population of the Mediterranean killifish Aphanius fasciatus was assessed using the male courtship behaviour as indicator of reproductive motivation under laboratory conditions. Timing of egg development was also checked to further support the existence of a tidal-related periodicity. Using a statistical model applied to the intensity of courtship behaviour measured over a two-month period, a semilunar periodicity was revealed, with two main peaks corresponding with full moons. Both behaviours and timing of egg development were consistent with a periodicity of 14 days, suggesting that the tidal cycle drives the reproduction of A. fasciatus in Northern Adriatic saltmarshes. The findings are assessed with a comparative approach within both European and North American transitional waters.

    To assess the biogeochemical effects of tidal restrictions on salt-marsh sulfur cycling and plant growth, cores of short-form Spartina alterniflora peat were desalinated and kept either waterlogged or drained in greenhouse microcosms. Changes in net Spartina production, and porewater and solid phase chemistry of treated cores were compared to natural conditions in the field collection site over a 21-mo period. Net production among treatments increased significantly in drained and waterlogged peat compared to field conditions during the first growing season. Constantly high sulfide in waterlogged cores accompanied reduced plant growth. Aeration invigorated growth in drained cores but led to oxidization of sulfide minerals and to lowered pH. During the second growing season, growth declined in the drained treatment, probably because of acidification and decreased dissolved inorganic nitrogen. Results are pertinent to the success of current wetland protection and restoration activities in the coastal zone.

    We determined the concentration of seston, particulate organic matter, and biological components (chlorophyll a, bacteria, and heterotrophic nanoflagellates) for <25 μm size fraction seston over five seasons in Canary Creek saltmarsh, Delaware Bay, USA. This material is the potential food resource for suspension-feeding ribbed mussels, Geukensia demissa, that inhabit the marsh intertidal zone. For eight tidal cycles each season we collected water six times at hourly intervals from mid-flood tide to mid-ebb tide. Although the concentration of seston did not vary seasonally, there were significant seasonal variations (analysis of variance, P<0.05) in seston components, with chlorophyll a concentration being highest in May and bacteria and heterotrophic nanoflagellates most abundant in August. Seston composition also varied within each tidal cycle with a magnitude as great as the seasonal variation. We conclude that ribbed mussels are subject to an unpredictable food supply that varies in composition and concentration on the order of hours and days. In contrast to the pronounced temporal changes, seston characteristics did not differ significantly among sampling locations within the marsh, or between samples collected close to the sediment surface and from the upper water column. Resuspension of sediment particles caused by tidal flow was not evident in tidal creeks and there were no dominant patterns in total seston concentration corresponding to tidal stages (flood tide, high slack water, and ebb tide) over the five sampling months. The abundance of biological components in the seston, including chlorophyll a, bacteria, and heterotrophic nanoflagellates, were significantly greater during high flood tide and high slack water than during ebb tide. The decline of biological components, particularly chlorophyll a in the ebb tide, indicates that this temperate saltmarsh imported organic material produced in the Delaware estuary.

    2012 has been an exciting year in the UK with substantial development on every front - research, clinical, industry and government. In particular, the focus has now moved to encompass far more post-research activities, with the continued enrolment of patients onto two pioneering Phase I clinical trials: ReNeuron's ReN001 stem cell therapy for stroke (PISCES) in Southern General Hospital, Greater Glasgow and Advanced Cell Technology's retinal pigment epithelial cells derived from human embryonic stem cells for Stargardts macular dystrophy and dry age-related macular degeneration at Moorfields Eye Hospital, London. The funding landscape for the sector has evolved from previous years to more fully embrace development and translation, including the provision of £180 million available for biomedical research via the Biomedical Catalyst Fund (joint Technology Strategy Board and Medical Research Council [MRC] funding) and a further £25 million through the UK Research Council's UK Regenerative Medicine Platform initiative, as well as ongoing developments with the Cell Therapy Catapult, which all act to further encourage a pan-UK collaborative environment. Overall, the UK cell therapy community continues to thrive and impact heavily upon the worldwide sector, with an established research base, a solid approach to translation and a small but growing commercial sector that is going from strength to strength.

    Saltmarsh is one of the important communities of wetlands, however, due to a range of pressures, it has been declared as an EEC (Ecological Endangered Community) in Australia. In order to correctly identify different saltmarsh species, development of spectral libraries of saltmarsh species is essential to monitor this EEC. Hyperspectral remote sensing, can explore the area of wetland monitoring and mapping. The benefits of Hyperion data to wetland monitoring have been studied at Hunter Wetland Park, NSW, Australia. After exclusion of bad bands from the original data, an atmospheric correction model was applied to minimize atmospheric effect and to retrieve apparent surface reflectance for different land cover. Large data dimensionality was reduced by Forward Minimum Noise Fraction (MNF) algorithm. It was found that first 32 MNF band contains more than 80% information of the image. Pixel Purity Index (PPI) algorithm worked properly to extract pure pixel for water, builtup area and three vegetation Casuarina sp., Phragmitis sp. and green grass. The result showed it was challenging to extract extreme pure pixel for Sporobolus and Sarcocornia from the data due to coarse resolution (30 m) and small patch size (<3 m) of those vegetation on the ground . Spectral Angle Mapper, classified the image into five classes: Casuarina, Saltmarsh (Phragmitis), Green grass, Water and Builtup area with 43.55 % accuracy. This classification also failed to classify Sporobolus as a distinct group due to the same reason. A high spatial resolution airborne hyperspectral data and a new study site with a bigger patch of Sporobolus and Sarcocornia is proposed to overcome the issue.

    Specifically radiolabeled (/sup 14/C-lignin)lignocellulose and (/sup 14/C-polysaccharide)lignocellulose from the salt-marsh cordgrass Spartina alterniflora were incubated with an intact salt-marsh sediment microbial assemblage, with a mixed (size-fractionated) bacterial assemblage, and with each of three marine fungi, Buergenerula spartinae, Phaeosphaeria typharum, and Leptosphaeria obiones, isolated from decaying S. alterniflora. The bacterial assemblage alone mineralized the lignin and polysaccharide components of S. alterniflora lignocellulose at approximately the same rate as did intact salt-marsh sediment inocula. The polysaccharide component was mineralized twice as fast as the lignin component; after 23 days of incubation, ca. 10% of the lignin component and 20% of the polysaccharide component of S. alterniflora lignocellulose were mineralized. Relative to the total sediment and bacterial inocula, the three species of fungi mediated only very slow mineralization of the lignin and polysaccharide components of S. alterniflora lignocellulose. Experiments with uniformly /sup 14/C-labeled S. alterniflora material indicated that the three fungi and the bacterial assemblage were capable of degrading the non-lignocellulosic fraction of S. alterniflora material, but only the bacterial assemblage significantly degraded the lignocellulosic fraction. Our results suggest that bacteria are the predominant degraders of lignocellulosic detritus in salt-march sediments.

    In the SW of Spain, just in the confluence of the mouths of the Tinto and Odiel River and in the vicinity of Huelva town, there is a big industrial complex which includes between others an industry devoted during more than 40 years to the production of phosphoric acid, by treating sedimentary phosphate rock by the so-called "wet acid method". As a by-product of the mentioned process it have been produced historically huge amounts of a compound called phosphogypsum, which composition is mostly di-hydrate calcium sulphate containing some of the impurities of heavy metals and natural radionuclides originally present in the raw material. Due to the lack of market for this by-product, it has been mostly piled over some salt-marshes located in the vicinity of the industry, on the bank of the Tinto River. About 100 million tons of phosphogypsum have been piled in an area covering more than 1000 hectares, constituting a clear environmental and radiological anomaly in the zone. The phosphogypsum piles set do not conform obviously a close system. They are interacting with the nearby environment mostly by leaching waters releases from the waters accumulated in them either for its previous use in transporting in suspension the PG from the factory or by rainfall. These waters leaks contain in solution enhanced amounts of heavy metals and radionuclides that can provoke the chemical and radioactive contamination in surroundings soil and salt-marshes areas. In this communication the radioactive influence by the phosphogypsum piles in the surrounding terrestrial environment is evaluated. This contamination is mostly due to radionuclides belonging to the uranium series, which are present originally in the raw material treated in the industry, and afterwards in the generated phosphogypsum, in enhanced amounts in relation to typical soils. In addition, the different dynamics and behavior of different radionuclides will be discussed and analyzed. The gained information in this study

  18. The mutual influence of biotic and abiotic components on the long-term ecomorphodynamic evolution of salt-marsh ecosystems

    Salt marshes are coastal ecosystems characterized by high biodiversity and rates of primary productivity, providing fundamental ecosystem services. Salt-marsh ecosystems are important indicators of environmental change as the dynamics are governed by interacting physical and biological processes, whose intertwined feedbacks critically affect the evolution. Settling deposition of inorganic sediment allows the platform to reach a threshold elevation for vegetation encroachment; the presence of vegetation then intensifies rates of accretion, thus, enhancing the resilience of marshes to increasing rates of sea level rise (SLR). The results from a two-dimensional numerical model, accounting for biotic and geomorphic processes, show that different morphological evolutionary regimes are followed depending on marsh biological processes. The average marsh elevation within the tidal frame decreases with increasing rates of SLR, decreasing availability of sediment, and decreasing productivity of vegetation. The spatial variability in platform elevations increases with increasing rates of SLR, increasing availability of sediment, and decreasing productivity of vegetation. Supply-limited settings tend to develop uniform marsh surface elevations, whereas supply-rich settings tend to develop patterns of sedimentation where large heterogeneities in marsh surface elevations occur. The complexity observed in tidal geomorphological patterns is deemed to arise from the mutual influence of biotic and abiotic components. The fate of tidal landforms and their possible geomorphological restoration should, thus, be addressed through approaches which explicitly incorporate bio-morphodynamic processes.

    An important requirement of the safety assessment for a geological disposal facility (GDF) for radioactive waste is to be able to demonstrate the long-term chemical stability of the groundwater system at repository depth over the long period of time during which the waste will be a hazard, typically up to one million years. Of particular concern in the UK is the potential for oxidising groundwater to penetrate to repository depth during periods of glaciation, thereby increasing the mobility of some transuranic radionuclides.Between 1990 and 1998, United Kingdom Nirex Limited carried out geological investigations into the suitability of a potential site in the Sellafield area of NW England, for a GDF for L/ILW. As part of these investigations, detailed petrological analysis of fracture mineralisation in 23 deep boreholes identified a complex sequence of mineralisation events referred to as ME1-ME9. The distribution of the ME9 calcite mineralisation correlates closely with present-day groundwater flows. The ME9 calcite has been studied in more detail to understand the evolution of the deep groundwater system. The morphology and growth zoning characteristics of the calcites reflects the groundwater chemistry. Freshwater calcites display c-axis flattened to equant crystals, and are non-ferroan and strongly zoned with Mn-rich and Mn-free bands. Deeper saline-zone calcites display c-axis elongated crystals, with high Mn:Fe and low Mn:Fe growth zones. Calcite in the transition zone between the saline and fresh groundwater display saline-type cores overgrown by freshwater-type calcite, indicating a small depression of the position of the transition zone during the growth of the calcites. Sr isotope ratios and fluid inclusion chemistry confirm a link between ME9 calcite and the present regional groundwater system. Modelling of the oxygen isotope data indicates that some growth zones in the ME9 calcite precipitated from groundwater potentially containing a significant

    Spartina alterniflora is one of the most serious invasive species in the coastal saltmarshes of China. Seeds are generally considered to be the main method for this species to colonise new habitat, but little is known quantitatively about the seed dispersal capacity and post-dispersal fate (i.e., germination and survival time). We measured the duration of seed flotation, seed persistence and seed germination of S. alterniflora in three intertidal zones [low intertidal zone (LIT), middle intertidal zone (MIT) and high intertidal zone (HIT)] in the Yangtze Estuary on the eastern coast of China. The results showed that (1) the flotation time of S. alterniflora seeds ranged from 3 to 13 days, and the values were higher in HIT and MIT than in LIT; (2) the period of seed germination was from February to June, mainly in March and April, and seed source affected seed germination as the values for seeds from HIT and MIT were much higher than those from LIT, while burial sites had no effect on germination percentages, and (3) the seed persistence was less than a year regardless of seed source, which was characterised by a transient seed bank, with values being higher in HIT and MIT than in LIT. Our results suggested that low marsh plants were far less able to produce successful seeds, or conversely, that the mid-marsh location had plants with the greatest seed production and seed mass, and the high- and mid-marsh plants had good seed floatation ability, germination and survival. Thus, plants in the mid-and high-marsh may contribute disproportionally to an invasion.

  2. Signatures of Biomass Burning Aerosols during a Smoke Plume Event from a Saltmarsh Wildfire in South Texas

    The most conventional and abundant tracers of biomass combustion in aerosol particles include potassium and biomarkers derived from thermally altered cellulose/hemicellulose (anhydrosugars) and lignin (methoxyphenols). However, little is known of the role of biomass combustion as a particulate source of major plant polymers to the atmosphere. Here, concentrations of "free" (solvent-extractable) anhydrosugars and methoxyphenols are compared to the yields of polymeric lignin oxidation products (LOPs) during a smoke plume event in Houston, Texas. Downwind aerosol samples (PM2.5) were collected prior to, during, and following a two-day wildfire event that burned ~5,000 acres of a spartina saltmarsh ecosystem in the McFaddin National Wildlife Refuge, 125 km southeast of Houston. In addition, charcoals of the burned plants were collected within a week of the fire at the wildfire site. HYSPLIT modeling shows that Houston was directly downwind of this wildfire during the peak of the burn, with an approximate travel time from source to aerosol sampling site of 12-16 hrs. Concentrations of all organic markers, K+, and Ca2+ jumped by a factor of 2-13 within 1-2 days of the start of the fire and dropped to pre-fire levels three days after the peak event. Source signatures of anhydrosugars and free methoxyphenols during the peak of the plume were identical to those of grass charcoals collected from the site, confirming the potential use of charcoals as endmembers for source input reconstruction during atmospheric transport. An enrichment factor of 20 in the anhydrosugar to methoxyphenol ratio of aerosols vs. charcoals can partially be explained by differences in degradation rate constants between the two biomarker groups. Polymeric LOP comprised 73-91% of all lignin material in the aerosols, pointing to fires as major sources of primary biogenic aerosol particles and confirming an earlier study that lignin phenols in atmospheric particles occur predominantly in polymeric form.

    Nitrogen-fixing bacteria were isolated from sediments and water of a saltmarsh lagoon on the west coast of South Africa, and characterized according to factors that regulate nitrogen fixation in the marine environment. The majority of isolates were assigned to the Photobacterium or Vibrio genera on the basis of physiological and biochemical characteristics. One isolate was further assigned to the species Vibrio diazotrophicus. Carbohydrate utilization by each diazotrophic isolate was examined. Abilities of the isolates to utilize a range of mono-, di-, and polysaccharides largely reflected the predicted availability of organic carbon and energy in the lagoon, except that chitin was not utilized. Biochemical tests on the utilization of combined nitrogen showed that one isolate could utilize nitrate, and that this strain was susceptible to full repression of nitrogenase activity by 10mM nitrate. Urease activity was not detected in any of the isolates. In the absence of molybdenum two of the isolates, a Photobacterium spp. and V. diazotrophicus, reduced acetylene to ethylene and ethane, a property frequently associated with the activity of alternative nitrogenases. Addition of 25µM molybdenum inhibited ethane production by V. diazotrophicus, but stimulated ethylene and ethane production by the Photobacterium isolate. Addition of 28µM vanadium did not appear to regulate ethane production by either strain. Assays of nitrogenase activity in sediments from which some isolates were obtained indicated that molybdenum was not limiting nitrogenase activity at naturally-occurring concentrations. Southern hybridizations of the chromosomes of these strains with the anfH and vnfH genes of Azotobacter vinelandii and the nifH gene of Klebsiella pneumoniae indicated the presence of only one nitrogenase in these isolates.

    Sea-level rise and sedimentation interact to control productivity on coastal salt marshes since the mean sea level influences flood frequency. Irregularly flooded marshes are inundated during spring and storm tides and during extended periods of north-easterly winds. The weak and irregular inundation in marshes may effect rates of decomposition, organic matter accumulation, and the vertical distribution of marsh vegetation. Whereas astronomical tides are predictable, wind driven tides depend on the strength and direction of the wind. Because these systems are stochastic, a non-hydrodynamic approach is used to describe the tides and determine the distribution of water depths. Here we present a description of salt-marsh inundation from mixed astronomical-wind driven tides that removes the astronomical forcing from water level records to determine the role of wind, storms, and forecasting of stochastic platform wetting. Using a 3 year record of water level and wind from sites in Carteret County, North Carolina, we calculate the mean high water (MHW) level and the ratio of inundation for a given elevation and corresponding macrophyte. The frequency of inundation or marsh platform wetting will vary from the frequency of MHW level, yet it is this stochastic wetting process that determines productivity and plant distribution since infrequent flooding may cause stress or hypersaline conditions. An ARIMA model is used to describe this higher order structure of the inundation signal. Wind can be described as an AR1 and a transfer function model is used to determine the dynamic response of the effect of noise and sustained winds on water levels. Harmonic analysis is also performed for comparison of predicted water levels using various tidal constituents to determine the phases and amplitudes and to explore model simplification.

    Invasive plants acting as habitat modifiers in coastal wetlands can have extensive ecological impacts. Control of invasive plants often relies on herbicides, although little is known about subsequent environmental impacts. Studying effects of herbicides on non-target species and long-term cascading consequences may yield insights into the ecology of invasive species by revealing interactions with native species. We conducted a long-term field experiment measuring effects of treating the invasive saltmarsh grass, Spartina anglica, with the herbicide Fusilade Forte®. No changes in sedimentary macrofaunal abundances or species richness, diversity, or assemblages were detected 1-2 months after spraying, despite known toxicity of Fusilade Forte® to fauna. This lack of impact may have been due to low exposure, since the herbicide was taken up primarily by plant leaves, with the small amount that reached the sediment hydrolyzing rapidly. Six months after spraying, however, total macrofauna in treated plots was more than four times more abundant than in unsprayed control plots, due to a fifteen-fold increase in annelids. This population growth correlated with increased sedimentary organic matter in treated plots, likely due to decomposition of dead S. anglica leaves serving as food for annelids. After another year, no differences in macrofauna or organic matter remained between treatments. The indirect effect on annelid populations from herbicide treatment could benefit management efforts by providing greater food resources for wading birds, in addition to improving birds' access to sediments by reducing plant cover. This study shows that an invasive grass can have a significant impact on native fauna through food-web interactions, influenced by herbicide usage.

    Anaerobic ammonium oxidation (anammox) as an important nitrogen removal pathway has been investigated in intertidal marshes. However, the rhizosphere-driven anammox process in these ecosystems is largely overlooked so far. In this study, the community dynamics and activities of anammox bacteria in the rhizosphere and non-rhizosphere sediments of salt-marsh grass Spartina alterniflora (a widely distributed plant in estuaries and intertidal ecosystems) were investigated using clone library analysis, quantitative PCR assay, and isotope-tracing technique. Phylogenetic analysis showed that anammox bacterial diversity was higher in the non-rhizosphere sediments (Scalindua and Kuenenia) compared with the rhizosphere zone (only Scalindua genus). Higher abundance of anammox bacteria was detected in the rhizosphere (6.46 × 10(6)-1.56 × 10(7) copies g(-1)), which was about 1.5-fold higher in comparison with that in the non-rhizosphere zone (4.22 × 10(6)-1.12 × 10(7) copies g(-1)). Nitrogen isotope-tracing experiments indicated that the anammox process in the rhizosphere contributed to 12-14 % N2 generation with rates of 0.43-1.58 nmol N g(-1) h(-1), while anammox activity in the non-rhizosphere zone contributed to only 4-7 % N2 production with significantly lower activities (0.28-0.83 nmol N g(-1) h(-1)). Overall, we propose that the rhizosphere microenvironment in intertidal marshes might provide a favorable niche for anammox bacteria and thus plays an important role in nitrogen cycling.

    Fluoride concentrations in eastern UK rivers (the Humber, Tweed, Wear, Great Ouse and Thames) are described based on information collected within the Land-Ocean Interaction Study (LOIS) and by the Environment Agency (EA) of England and Wales. The results show varied fluoride concentrations across the region, with a range from <0.01 to >10 mg l(-1); and mean, median and range in mean concentrations of 0.30, 0.21 and 0.05-3.38 mg l(-1) (excluding one outlier point), respectively. Within the main rivers and tributaries, the mean fluoride concentration varied from approximately 0.5 to over 2 mg l(-1) and the highest values occurred within the Don basin (Don, Dearne and Rother) and parts of the Trent basin (upper Tame and mid-upper Derbyshire Derwent) in highly industrialised and urbanised areas (Sheffield and Rotherham in the Don basin; Birmingham and Derby on the Trent). For localised inputs to the rivers, fluoride concentrations were slightly higher, and considerably higher in one outlier case. Correspondingly, the other rivers examined typically had mean fluoride concentrations between approximately 0.2 and 0.5 mg l(-1), but fluoride concentrations were lower in the headwater areas. As there is much less information on fluoride levels in upland areas, extensive data collected as part of an acid waters survey are used to show that fluoride concentrations are generally less than 0.1 mg l(-1) for the upland UK. The data are summarised in terms of both fluoride concentrations and flux, and the values are cross-referenced to other determinands collected within LOIS. The high positive correlation with boron and negative correlation with flow show the importance of point source (sewage) inputs of fluoride, while strong positive correlations between fluoride and barium indicate the relative importance of vein mineralisation in the bedrock in supplying fluoride to the waters of the Yorkshire Ouse and its tributaries. There seems to be some process that limits the fluoride

  15. Integrated assessment of socioeconomic and climate change on the Broads National Park, UK, using the 'Regional Impact Simulator'

    The Broads National Park, located in the east of England is the UK's only wetland National Park. Located in a low-lying area of intensive arable agriculture in the driest part of England, it faces many challenges. The 'Regional Impact Simulator' is a user friendly software tool designed to allow UK stakeholders to perform regional integrated assessments of the effects of socio-economic and/or climate change on important sectors and resources. This includes assessment of agriculture, water resources, biodiversity and coastal and river flooding. The development of this regional tool arose from the need to further develop the methods applied in the first local to regional integrated assessment in the UK, which was limited by very long run times, a limited number of simulations, incomplete linkages between models and no allowance for scenario uncertainty. Using the 'Regional Impact Simulator' for a range of socio-economic and emissions scenarios for the 2050s, The Broads in will face a diverse range of challenges related to: 1) Changes in coastal and fluvial flood risk - increased sea level and fluvial flows will increase flood risk for current flood defences; 2) Changing agricultural practices, associated with changing farmer responses to policy, will affect nutrient losses and habitats 3) Changes in water abstraction and discharge - irrigation demand will increase as water resources decrease. However future water availability is a consequence of both societal and policy priorities towards abstraction, and the changing patterns of urbanization and water usage; 4) Changes in habitats especially coastal habitats - saltmarsh will tend to be lost due to sea level rise, although managed realignment may increase stocks at the expense of coastal grazing marshes Socio-economic changes can be as (if not more) important than direct climate change-induced impacts, but the impacts of these changes depend on the choices society makes (e.g. flood defence policy; water demand

  16. The puzzle of high heads beneath the West Cumbrian coast, UK: a possible solution

    A region of high heads within the Borrowdale Volcanic Group (BVG; a fractured crystalline rock) beneath the coastal plain of West Cumbria, England (UK), is identified as a possible relic left over by the Late Devensian ice sheet. It was found during investigations in the 1990s. Contemporary modelling work failed to produce a satisfactory explanation of the high heads compatible with the `cold recharge' isotopic signature of the groundwater. This study has reassessed the original hydraulic testing results. By plotting density-adjusted heads versus their depth below the water table in the immediate vicinity of the borehole in which they were measured, a depth profile resembling a `wave' was revealed with a peak value located at 1,100 m depth. The possibility that this wave represents relic heads from the last major ice sheet has been assessed using one-dimensional mathematical analysis based on a poroelastic approach. It is found that a wet-based ice sheet above the West Cumbrian coast was probably thick enough and sufficiently long-lasting to leave such relic heads providing that the hydraulic diffusivity of the BVG is in the order of 10-6 m s-1. Initial assessment 20 years ago of the long-interval slug tests suggested that such low values are not likely. More recent interpretation argues for such low values of hydraulic diffusivity. It is concluded that ice sheet recharge is the most likely cause of the raised heads, that the BVG contains significant patches of very low conductivity rock, and that long-interval single-hole tests should be avoided in fractured crystalline rock.

    Intensification of agriculture has resulted in increased soil degradation and erosion, with associated pollution of surface waters. Small field wetlands, constructed along runoff pathways, offer one option for slowing down and storing runoff in order to allow more time for sedimentation and for nutrients to be taken up by plants or micro-organisms. This paper describes research to provide quantitative evidence for the effectiveness of small field wetlands in the UK landscape. Ten wetlands were built on four farms in Cumbria and Leicestershire, UK. Annual surveys of sediment and nutrient accumulation in 2010, 2011 and 2012 indicated that most sediment was trapped at a sandy site (70 tonnes over 3 years), compared to a silty site (40 tonnes over 3 years) and a clay site (2 tonnes over 3 years). The timing of rainfall was more important than total annual rainfall for sediment accumulation, with most sediment transported in a few intense rainfall events, especially when these coincided with bare soil or poor crop cover. Nutrient concentration within sediments was inversely related to median particle size, but the total mass of nutrients trapped was dependent on the total mass of sediment trapped. Ratios of nutrient elements in the wetland sediments were consistent between sites, despite different catchment characteristics across the individual wetlands. The nutrient value of sediment collected from the wetlands was similar to that of soil in the surrounding fields; dredged sediment was considered to have value as soil replacement but not as fertiliser. Overall, small field wetlands can make a valuable contribution to keeping soil out of rivers.

    Bacillus thuringiensis var. israelensis (Bti) is commonly used for selective control of larval populations of mosquitoes in coastal wetlands. A two year-study was implemented to investigate whether repeated treatments with Bti applied either as a liquid (VectoBac® 12AS) or a water-dispersible granule (VectoBac® WG) formulation may affect the abundance and diversity of non-target aquatic invertebrates in saltmarsh pools. Taxonomic composition of the invertebrate communities was typical of brackishwater intermittent ecosystems, with a dominance of annelids, crustaceans and nematocerans. Conditions were contrasted between the two years of the survey, both in terms of annual cumulative rainfall and rainfall distribution throughout the year. As a consequence, the hydroperiod and some other environmental characteristics associated with pool drying played a major role in the dynamics of the invertebrate community. In summer 2006, pool drying reduced the abundance of the polychaete worm Nereis diversicolor, of the amphipod crustacean Corophium volutator and of chironomid larvae. These taxa were able to recolonize rapidly the pools after flooding in September 2006. In 2007, rainfall was more regularly distributed across the year, and the pools did not get dry. Hydrozoans, Chironomini and Orthocladiinae larvae, and oligochaetes were more abundant in treated than in control pools, especially in VectoBac® WG-treated pools. No adverse effects of the treatments were shown on the abundance of N. diversicolor, C. volutator and midge larvae, suggesting that the availability of these food sources for birds was not negatively affected by Bti applications. It is concluded that, as currently performed in Western France coastal wetlands, land-based treatments of saltmarsh pools for larval mosquito control with Bti, used either as VectoBac® 12AS or VectoBac® WG, did not adversely impact non-target aquatic invertebrate communities.

    Salt marshes are ubiquitous features of the tidal landscape governed by mutual feedbacks among processes of physical and biological nature. Improving our understanding of these feedbacks and of their effects on tidal geomorphological and ecological dynamics is a critical step to address issues related to salt-marsh conservation and response to changes in the environmental forcing. In particular, the spatial variation of organic and inorganic soil production processes at the marsh scale, a key piece of information to understand marsh responses to a changing climate, remains virtually unexplored. In order to characterize the relative importance of organic vs. inorganic deposition as a function of space, we collected 33 shallow soil sediment samples along three transects in the San Felice and Rigà salt marshes located in the Venice lagoon, Italy. The amount of organic matter in each sample was evaluated using Loss On Ignition (LOI), a hydrogen peroxide (H2O2) treatment, and a sodium hypochlorite (NaClO) treatment following the H2O2 treatment. The grain size distribution of the inorganic fraction was determined using laser diffraction techniques. Our study marshes exhibit a weakly concave-up profile, with maximum elevations and coarser inorganic grains along their edges. The amount of organic and inorganic matter content in the samples varies with the distance from the marsh edge and is very sensitive to the specific analysis method adopted. The use of a H2O2+NaClO treatment yields an organic matter density value which is more than double the value obtained from LOI. Overall, inorganic contributions to soil formation are greatest near the marsh edges, whereas organic soil production is the main contributor to soil accretion in the inner marsh. We interpret this pattern by considering that while plant biomass productivity is generally lower in the inner part of the marsh, organic soil decomposition rates are highest in the better aerated edge soils. Hence the higher

    Over the years, the LSA role and function have developed and strengthened significantly and it is crucial that this development continues in the new NHS. The biennial LSAMO UK conference which is entitled Future proofing supervision will launch the strategic plan for 2012-2015. It is essential that LSAMOs and supervisors of midwives (SoMs) look to the future to continue to maintain safety and protect the public, but within a modernised forward thinking framework. The forum will work collaboratively to encourage a greater consistency in the provision of supervision to ensure the standards set by the NMC for the LSAs and the supervision of midwives are met. Protecting the public and supporting safe midwifery practice will continue to be the driving principles behind the LSAMO UK forum's work plan. The specific challenges to LSAMOs will be to continue providing leadership and support and be pivotal in addressing the future significant challenges faced by the NHS throughout the UK.

    2016-04-15

    Stable isotope analyses of the abundant infaunal polychaete Hediste diversicolor, recognised as an indicator of sewage pollution, support the hypothesis that nutrient enrichment promotes surface deposit feeding, over suspension feeding and predation. At sewage-polluted sites in three estuaries in SE England Hediste mainly consumed microphytobenthos, sediment organic matter and filamentous macroalgae Ulva spp. At cleaner sites Hediste relied more on suspension feeding and consumption of Spartina anglica. There were no consistent differences in Hediste densities between the polluted and cleaner sites, probably because of increased densities at the cleaner sites too, facilitated by the planting of Spartina and nitrogen enrichment there too, including from agricultural run-off. Increased nutrient enrichment and the artificial availability of Spartina have probably increased densities of, and deposit-feeding by, Hediste in the past half-century and contributed indirectly to saltmarsh losses, since deposit-feeding by Hediste has been implicated in recent saltmarsh erosion in SE England.

Major adjustments are taking place in Europe following the opening up of the Eastern European countries. The consequences of the illegal movement of wastes and its mistreatment and disposal are now recognised within the European Union. The UK as a member State is well aware of the consequences which arise from the lack of proper waste management.

    Athletes obtain nutritional information from their coaches, yet their competency in this area is lacking. Currently, no research exists in the UK which has a different coach education system to many other countries. Therefore, the aim of this study was to evaluate the sports nutrition knowledge of UK coaching certificate (UKCC) level 2 and 3, hockey and netball qualified coaches. All coaches (n = 163) completed a sports nutrition questionnaire to identify: (a) if they provided nutritional advice; (b) their level of sport nutrition knowledge; and (c) factors that may have contributed to their level of knowledge. Over half the coaches provided advice to their athletes (n = 93, 57.1%), even though they were not competent to do so. Coaches responded correctly to 60.3 ± 10.5% of all knowledge questions with no differences between those providing advice and those who did not (p > 0.05). Those coaches who had undertaken formal nutrition training achieved higher scores than those who had not (p < 0.05).

    The UK is globally recognised as strong in Photonics. However its Photonics sector is fragmented and the size and sectors of interest have not previously been established. The UK government has instigated the formation of the Photonics Knowledge Transfer Network (PKTN) to bring the Photonics community together. The UK features in Defence & Security; Communications; Measurement; Medical Technology; Lighting; Solar Energy; Information Technology and Flat Panels. This expertise is scattered through out the UK in geographic areas each with a breadth of Photonic interests. The PKTN has mapped the UK capability in all Photonics sectors. This paper will present the capability of the Companies, Research Institutions and Infrastructure making up the Defence & Security Photonics scene in the UK. Large Defence companies in the UK are well known throughout the world. However, there are a large number of SMEs, which may not be as well known in the supply chain. These are being actively encouraged by the UK MoD to engage with the Defence & Security Market and shall be discussed here. The presentation will reference a number of organisations which help to fund and network the community, such as the Defence Technology Centres. In addition the Roadmap for Defence & Security in the UK, produced for the UK Photonics Strategy (July 2006) by the Scottish Optoelectronics Association will be described and the plans in taking it forward under the PKTN will be revealed.

    Understanding the biogeochemical behaviour and potential mobility of actinides in soils and groundwater is vital for developing remediation and management strategies for radionuclide-contaminated land. Pu is known to have a high Kd in soils and sediments, however remobilization of low concentrations of Pu remains a concern. Here, some of the physicochemical properties of Pu and the co-contaminant, Am, are investigated in contaminated soils from Aldermaston, Berkshire, UK, and the Esk Estuary, Cumbria, UK, to determine their potential mobility. Sequential extraction techniques were used to examine the host-phases of the actinides in these soils and their susceptibility to microbiological leaching was investigated using acidophilic sulphur-oxidising bacteria. Sequential extractions found the majority of (239,240)Pu associated with the highly refractory residual phase in both the Aldermaston (63.8-85.5 %) and Esk Estuary (91.9-94.5%) soils. The (241)Am was distributed across multiple phases including the reducible oxide (26.1-40.0%), organic (45.6-63.6%) and residual fractions (1.9-11.1%). Plutonium proved largely resistant to leaching from microbially-produced sulphuric acid, with a maximum 0.18% leached into solution, although up to 12.5% of the (241)Am was leached under the same conditions. If Pu was present as distinct oxide particles in the soil, then (241)Am, a decay product of Pu, would be expected to be physically retained in the particle. The differences in geochemical association and bioleachability of the two actinides suggest that this is not the case and hence, that significant Pu is not present as distinct particles. These data suggest the majority of Pu in the contaminated soils studied is highly recalcitrant to geochemical changes and is likely to remain immobile over significant time periods, even when challenged with aggressive "bioleaching" bacteria.

  12. Palaeoenvironment of braided fluvial systems in different tectonic realms of the Triassic Sherwood Sandstone Group, UK

    Fluvial successions comprising the fills of sedimentary basins occur in a variety of tectonic realms related to extensional, compressional and strike-slip settings, as well as on slowly subsiding, passive basin margins. A major rifting phase affected NW Europe during the Triassic and resulted in the generation of numerous sedimentary basins. In the UK, much of the fill of these basins is represented by fluvial and aeolian successions of the Sherwood Sandstone Group. Additionally, regions that experienced slow rates of Mesozoic subsidence unrelated to Triassic rifting also acted as sites of accumulation of the Sherwood Sandstone Group, one well-exposed example being the eastern England Shelf. The fluvial depositional architecture of deposits of the Sherwood Sandstone Group of the eastern England Shelf (a shelf-edge basin) is compared with similar fluvial deposits of the St Bees Sandstone Formation, eastern Irish Sea Basin (a half-graben). The two studied successions represent the preserved deposits of braided fluvial systems that were influenced by common allogenic factors (climate, sediment source, delivery style); differences in preserved sedimentary style principally reflect their different tectonics settings. Analysis of lithofacies and architectural elements demonstrates that both studied successions are characterized by amalgamated channel-fill elements that are recorded predominantly by downstream-accreting sandy barforms. The different tectonic settings in which the two braided-fluvial systems accumulated exerted a dominant control on preserved sedimentary style and long-term preservation potential. On the eastern England Shelf, the vertical stacking of pebbly units and the general absence of fine-grained units reflect a slow rate of sediment accommodation generation (18-19.4 m/Myr). In this shelf-edge basin, successive fluvial cycles repeatedly reworked the uppermost parts of earlier fluvial deposits such that only the lowermost channel lags tend to be

    The most widely used device for measuring rainfall is the rain gauge, of which the tipping bucket (TBR) is the most prevalent type. Rain gauges are considered by many to be the most accurate method currently available. The data they produce are used in flood-forecasting and flood risk management, water resource management, hydrological modelling and evaluating impacts on climate change; to name but a few. Rain gauges may provide the most accurate measurement of rainfall at a point in space and time, but they are subject to errors - and some gauges are more prone than others. The most significant error is the 'wind-induced undercatch'. This is caused by the gauge itself contributing to an acceleration of the wind speed near the orifice, which disturbs and distorts the airflow. The trajectories of precipitation particles are affected, resulting in an undercatch. Results from Computational Fluid Dynamics (CFD) simulations, presented herein, describe in detail the physical processes contributing to this. High resolution field measurements of rainfall and wind are collected at four field research stations in the UK. Each site is equipped with juxtaposed rain gauges with different funnel profiles, in addition to a WMO reference pit rain gauge measurement. These data describe the rainfall measurement uncertainty. The sites were selected to represent the prevalent rainfall regimes observed in the UK. Two research stations are on the west coast; which is prone to frontal weather systems and storms swept in from the Atlantic, often enhanced by orography. Two are located in the east. Rural lowland and upland areas are represented, both in the west and the east. Urban sites will also have significant undercatch problems but are outside the scope of this study. Data from the four research stations are analysed for the 2015 winter storms which caused devastating flooding in the west of the UK, particularly Cumbria and the Scottish Borders, where two of the sites are located.

  15. Impact of hurricane Isaac on recovery of saltmarshes affected by the BP oil spill in Barataria Bay in the Gulf of Mexico

    Saltmarshes of the Gulf of Mexico have a long history of being impacted by oil spills. The Deep Water Horizon BP Oil spill was the biggest spill in US history. Its effects are still noticeable on these coastal wetlands. While it is expected that over time these ecosystems will recover from oil spill impacts, disturbances can alter the pathway to recovery. In August 2012, hurricane Isaac traced the same path as the 2010 oil spill. We questioned whether the hurricane had a detrimental effect on the recovery of wetland communities previously affected by the oil spill. We analyzed AVIRIS hyperspectral imagery acquired over Bay Jimmy in Barataria Bay in September of 2010, in August of 2011, and after hurricane Isaac in October of 2012. We estimated oil and hurricane impact extent, and effects on plant stress based on change detection and trajectories of narrow band vegetation indexes. In September 2010, the oil impact extended 14m inland from the shore. Four plant stress indexes (NDVI, mNDVI, ANIR, ARed) and three water content indexes (NDII, WA980, WA1240) consistently showed that plant stress was significantly negatively correlated with distance from the shore. A year after the oil spill, in August 2011, we found that the vegetation was regenerating rapidly in more than 80% of the affected area. However, after hurricane Isaac, in October 2012, 24% of the 14-m green vegetation belt next to the shore disappeared under water in regions previously impacted by oil and 21% of the oil-free shoreline also lost its land to water. In the first 7 m adjacent to the shore, 38.5% of the land disappeared in oil-impacted zones and 32% in the oil-free zones. These results suggest that post-oil disturbance events can delay vegetation recovery in an already fragile wetland community.

  16. Variability of organic δ13C and C/N in the Mersey Estuary, U.K. and its implications for sea-level reconstruction studies

    Microfossil analysis (e.g. diatoms, foraminifera and pollen) represents the cornerstone of Holocene relative sea-level (RSL) reconstruction because their distribution in the contemporary inter-tidal zone is principally controlled by ground elevation within the tidal frame. A combination of poor microfossil preservation and a limited range in the sediment record may severely restrict the accuracy of resulting RSL reconstructions. Organic δ13C and C/N analysis of inter-tidal sediments have shown some potential as coastal palaeoenvironmental proxies. Here we assess their viability for reconstructing RSL change by examining patterns of organic δ13C and C/N values in a modern estuarine environment. δ13C and C/N analysis of bulk organic inter-tidal sediments and vegetation, as well as suspended and bedload organic sediments of the Mersey Estuary, U.K., demonstrate that the two main sources of organic carbon to surface saltmarsh sediments (terrestrial vegetation and tidal-derived particulate organic matter) have distinctive δ13C and C/N signatures. The resulting relationship between ground elevation within the tidal frame and surface sediment δ13C and C/N is unaffected by decompositional changes. The potential of this technique for RSL reconstruction is demonstrated by the analysis of part of an early Holocene sediment core from the Mersey Estuary. Organic δ13C and C/N analysis is less time consuming than microfossil analysis and is likely to provide continuous records of RSL change.

    Data on the temporal and spatial variations of 99Tc and 137Cs in UK coastal waters are provided from surveys carried out over the period 1993-1998; prior to and post the discharge of elevated quantities of 99Tc from the nuclear fuel reprocessing plant at Sellafield (Cumbria, UK). 99Tc seawater concentrations in the Irish Sea increased by more than an order of magnitude within the study period concomitant with the increase in discharges. 137Cs discharges were relatively low (˜0.3% of their peak values in the 1970s). Simplistically, the 137Cs distribution reflected varying hydrographic conditions superimposed upon the residual concentrations of a system approaching steady state. Differences between the 137Cs/ 99Tc ratio in Sellafield discharges and seawater indicate that 137Cs remobilisation, from sediments contaminated by large discharges in the 1970s, is presently the predominant (˜90%) source term to the water column. The 137Cs/ 99Tc ratio in the Irish Sea decreased significantly within the period of these surveys (e.g. reduced from ˜14 in 1993 to 0.4 in 1996, within the vicinity of Sellafield). However, it is difficult to extrapolate this information to assess the contribution from Sellafield in distant waters because the low levels of 137Cs are continuously perturbed by additional inputs during transit (e.g. remobilisation from sediments outside the Irish Sea). Examination of 99Tc data for the North Sea indicates that the leading edge of the first EARP pulse, entering via the Scottish coastal current, may have migrated to the limit of the current flowing south along the British coastal margin within 9 months. The estimated transfer factor (TF) for Sellafield discharges in this current is 52 Bq m -3/PBq annum -1 with transit times from Sellafield to the Pentland Firth and Lowestoft of ˜9 and ˜24 months, respectively. These transit times, derived from the 99Tc data, are significantly shorter than previous estimates based on 137Cs and 90Sr data from the 1970s

    Demands on our mental health services are growing as financial pressures increase. In addition, there are regular changes to service design and commissioning. The current political mantra is ‘more and more, of better quality, for less and less, please’. We suggest that mental health services need to actively respond to these constraints and that clinical transformation is needed to move towards a more sustainable system of healthcare. Emphasis on prevention, patient empowerment and leaner, greener services is required alongside more extensive use of technologies. Focusing on these areas will make mental health services more responsive to the challenges we face and serve to future-proof psychiatry in the UK. Services need to be delivered to provide maximum benefit to the health of our patients, but also to our society and the environment. PMID:25505629

    Objective To explore the experience of non-UK-qualified doctors in working within the regulatory framework of the General Medical Council (GMC) document Good Medical Practice. Design Individual interviews and focus groups. Setting United Kingdom. Participants Non-UK-qualified doctors who had registered with the GMC between 1 April 2006 and 31 March 2008, doctors attending training/induction programmes for non-UK-qualified doctors, and key informants involved in training and support for non-UK-qualified doctors. Main outcome measures Themes identified from analysis of interview and focus group transcripts. Results Information and support for non-UK qualified doctors who apply to register to work in the UK has little reference to the ethical and professional standards required of doctors working in the UK. Recognition of the ethical, legal and cultural context of UK healthcare occurs once doctors are working in practice. Non-UK qualified doctors reported clear differences in the ethical and legal framework for practising medicine between the UK and their country of qualification, particularly in the model of the doctor–patient relationship. The degree of support for non-UK-qualified doctors in dealing with ethical concerns is related to the type of post they work in. European doctors describe similar difficulties with working in an unfamiliar regulatory framework to their non-European colleagues. Conclusions Non-UK-qualified doctors experience a number of difficulties related to practising within a different ethical and professional regulatory framework. Provision of information and educational resources before registration, together with in-practice support would help to develop a more effective understanding of GMP and its implications for practice in the UK.

    A significant milestone for British and European science occurred today (July 8, 2002) when the Council of the European Southern Observatory (ESO) met in London. At this historical meeting, the United Kingdom was formally welcomed into ESO by the nine other member states. The UK, one of the leading nations in astronomical research, now joins one of the world's major astronomical organisations. UK astronomers will now be able to use the four 8.2-metre and several 1.8-metre telescopes that comprise the Very Large Telescope (VLT) facility located at the Paranal Observatory in the northern part of the Atacama desert in Chile, as well as two 4-m class telescopes and several smaller ones at the ESO La Silla Observatory further south. The UK will also benefit from increased involvement in the design and construction of the Atacama Large Millimetre Array (ALMA), a network of 64 twelve-metre telescopes also sited in Chile, and play a defining role in ESO's 100-metre Overwhelmingly Large Telescope (OWL). Sir Martin Rees , The Astronomer Royal, said, "Joining ESO is good for UK science, and I think good for Europe as well. It offers us access to the VLT's 8-m class telescopes and restores the UK's full competitiveness in optical astronomy. We're now guaranteed full involvement in ALMA and in the next generation of giant optical instruments - projects that will be at the forefront of the research in the next decade and beyond. Moreover, our commitment to ESO should enhance its chances of forging ahead of the US in these technically challenging and high profile scientific projects. UK membership of ESO is a significant and welcome outcome of this government's increasing investment in science". Prof. Ian Halliday , Chief Executive of the Particle Physics and Astronomy Research Council (PPARC), the UK's strategic science investment agency said, "The United Kingdom already participates in Europe's flagship particle physics research and the space science research programmes through

    The project is a consortium based activity involving researchers from the UK institutions of the Universities of Surrey, St. Andrews, Leeds, Warwick, and Southampton, as well as the commercial research institution QinetiQ. The aims of the project are to progress the state of the art in Silicon Photonics, in the areas of waveguides, modulators, couplers, detectors, Raman processes, and integration with electronics. Thus the field is vast, and impossible to cover comprehensively in one project, nor indeed in one paper. The programme is run on a truly collaborative basis, with members from each institution running one or more work packages within the project, each co-ordinating work from their own plus other institutions. To date, the most well developed work has emerged from the activity on basic waveguides and their characteristics, the modulator activity, optical filters, and work on Raman Amplifiers. This work will be the main focus of this paper, but an attempt will be made to update the audience on the remaining activities within the project. By the nature of the project, much of the work is medium term, and hence some activities are not expected to yield viable results until at least next year, hence the concentration on some activities rather than all activities at this stage.

    The Australian Government is wise to examine other health care systems as it strives to improve the quality of care and address rising costs to both governments and individuals. Focus is currently on the United Kingdom, whose National Health Service (NHS) stands out as one that delivers good care at a reasonable price to all who need it. The Australian and UK systems have many similarities: universal access, tax payer support, no or low cost at point of delivery, and good population health outcomes. They also face similar pressures on services from aging, increasingly unwell yet expectant populations.However, there are also differences, largely in the way that health care is funded, organised and delivered. The NHS is a huge system for 60 million people in four home countries with diverging policies. Within England, the system is managed through 10 strategic health authorities, each responsible for about 5 million people and having the right to interpret national policy. Population based health care, including tertiary care, is funded locally via primary care trusts. PMID:19283244

    Background: Telemedicine is a new way of delivering health care to people, particularly in remote areas. The UK has experienced a surge of telematic projects in recent years. However, there is little information available in the literature regarding the past and present of telemedicine in the UK. Objectives: To evaluate the state of telemedicine in the UK. Methods: All the projects that took place in UK since 1991 were considered for the study and evaluated according to the population and area served. Results: A total of 216 projects were identified. The number of projects was highest in England (172). Emergency medicine, medical specialties, and educational projects received most consideration (9.7% each). With the exception of Wales, the number of projects increased steadily with time. The projects, when correlated in accordance with the area (per 10 000 sq km) and population (per million), were found to be highest in England (49.5%) and Northern Ireland (36.2%) respectively. No dedicated educational project took place in Scotland, Northern Ireland, and Wales. Conclusions: The UK embraced telemedicine in the early 1990s and the overall growth had been steady. Scotland, in spite of being the most likely beneficiary in UK, has lagged behind in telemedicine schemes and merits more projects. The issue of tele-education needs urgent review. Multisite trials and a combined approach involving the government, health professionals, technologists, and patients' representatives would facilitate such developments and help widen the application of telemedicine.

    1.Malaria is the tropical disease most commonly imported into the UK, with 1300-1800 cases reported each year, and 2-11 deaths. 2. Approximately three quarters of reported malaria cases in the UK are caused by Plasmodium falciparum, which is capable of invading a high proportion of red blood cells and rapidly leading to severe or life-threatening multi-organ disease. 3. Most non-falciparum malaria cases are caused by Plasmodium vivax; a few cases are caused by the other species of plasmodium: Plasmodium ovale, Plasmodium malariae or Plasmodium knowlesi. 4. Mixed infections with more than one species of parasite can occur; they commonly involve P. falciparum with the attendant risks of severe malaria. 5. There are no typical clinical features of malaria; even fever is not invariably present. Malaria in children (and sometimes in adults) may present with misleading symptoms such as gastrointestinal features, sore throat or lower respiratory complaints. 6. A diagnosis of malaria must always be sought in a feverish or sick child or adult who has visited malaria-endemic areas. Specific country information on malaria can be found at http://travelhealthpro.org.uk/. P. falciparum infection rarely presents more than six months after exposure but presentation of other species can occur more than a year after exposure. 7. Management of malaria depends on awareness of the diagnosis and on performing the correct diagnostic tests: the diagnosis cannot be excluded until more than one blood specimen has been examined. Other travel related infections, especially viral haemorrhagic fevers, should also be considered. 8. The optimum diagnostic procedure is examination of thick and thin blood films by an expert to detect and speciate the malarial parasites. P. falciparum and P. vivax (depending upon the product) malaria can be diagnosed almost as accurately using rapid diagnostic tests (RDTs) which detect plasmodial antigens. RDTs for other Plasmodium species are not as reliable. 9

    This paper presents estimates of rates of mean sea level (MSL) change around the UK, based on a larger tide gauge data set and more accurate analysis methods than have been employed so far. The spatial variation of the trend in MSL is found to be similar to that inferred from geological information and from advanced geodetic techniques, which is a similar conclusion to that arrived at in the previous studies. The tide gauge MSL trends for 1901 onwards are estimated to be 1.4 +/- 0.2 mm yr-1 larger than those inferred from geology or geodetic methods, suggesting a regional sea level rise of climate change origin several one-tenths of mm per year lower than global estimates for the 20th century. However, UK MSL change cannot be described in terms of a simple linear increase alone but includes variations on interannual and decadal timescales. The possible sources of variation in a `UK sea level index' are explored. Air pressure is clearly one such possible source but its direct local forcing through the `inverse barometer' accounts for only one-third of the observed variability. A number of larger scale atmospheric and ocean processes must also play important roles, but modelling them satisfactorily and separating the individual contributions present a major challenge. As regards future regional UK sea level changes, we conclude that there is no basis for major modification to existing projections for the 2080s included in the 2002 UK Climate Impacts Programme studies.

  16. UK Announces Intention to Join ESO

    NASA Astrophysics Data System (ADS)

    2000-11-01

    Summary The Particle Physics and Astronomy Research Council (PPARC) , the UK's strategic science investment agency, today announced that the government of the United Kingdom is making funds available that provide a baseline for this country to join the European Southern Observatory (ESO) . The ESO Director General, Dr. Catherine Cesarsky , and the ESO Community warmly welcome this move towards fuller integration in European astronomy. "With the UK as a potential member country of ESO, our joint opportunities for front-line research and technology will grow significantly", she said. "This announcement is a clear sign of confidence in ESO's abilities, most recently demonstrated with the construction and operation of the unique Very Large Telescope (VLT) on Paranal. Together we will look forward with confidence towards new, exciting projects in ground-based astronomy." It was decided earlier this year to place the 4-m UK Visible and Infrared Survey Telescope (VISTA) at Paranal, cf. ESO Press Release 03/00. Following negotiations between ESO and PPARC, a detailed proposal for the associated UK/ESO Agreement with the various entry modalities will now be presented to the ESO Council for approval. Before this Agreement can enter into force, the ESO Convention and associated protocols must also be ratified by the UK Parliament. Research and key technologies According to the PPARC press release, increased funding for science, announced by the UK government today, will enable UK astronomers to prepare for the next generation of telescopes and expand their current telescope portfolio through membership of the European Southern Observatory (ESO). The uplift to its baseline budget will enable PPARC to enter into final negotiations for UK membership of the ESO. This will ensure that UK astronomers, together with their colleagues in the ESO member states, are actively involved in global scale preparations for the next generation of astronomy facilities. among these are ALMA

    PubMed

    Harris, Benjamin H L; Walsh, Jason L; Lammy, Simon

    2015-02-01

    From senior school through to consultancy, a plethora of assessments shape medical careers. Multiple methods of assessment are used to discriminate between applicants. Medical selection in the UK appears to be moving increasingly towards non-knowledge-based testing at all career stages. We review the evidence for non-knowledge-based tests and discuss their perceived benefits. We raise the question: is the current use of non-knowledge-based tests within the UK at risk of undermining more robust measures of medical school and postgraduate performance?

  19. Under pressure: homeopathy UK and its detractors.

    PubMed

    Milgrom, Lionel R

    2009-08-01

    Though homeopathy has been in successful and continuous use for well over 200 years, in the United Kingdom it is under growing pressure, from scientific detractors and sections of the media. As such, homeopathy's free National Health Service provision is threatened because it is derided as 'unproven', 'unscientific', and even 'deadly'. While refuting these and other detractions, this paper considers possible reasons for the current plight of homeopathy UK. Thus, the current attacks against homeopathy should be viewed more in the context of the globalised pharmaceutical industry which is itself in crisis, and a succession of UK governments seemingly supine in the face of legislation originating from the European Union.

    Forbes, A E; Zochowski, W J; Dubrey, S W; Sivaprakasam, V

    2012-12-01

    The recent high-profile death of a British Olympic rower from leptospirosis has raised awareness to this uncommon but potentially fatal disease. The re-emergence of the disease abroad is well documented in the literature, but less is known about cases in the UK. The increase in participation in water sports, foreign travel and often a combination of the two, has increased the exposure of tourists subsequently returning to the UK from areas of high prevalence. Leptospirosis is a zoonotic infection. The bacteria are shed in the urine of animals to the environment from where humans are infected by incidental hosts. There is a wide spectrum of severity of symptoms, from a self-limiting febrile illness to fatal pulmonary haemorrhage, renal or liver failure. It is thought that cases remain unrecognized every year in the UK, largely due to the mild nature of symptoms and the wide differential for febrile illness and partly due to lack of awareness among clinicians. This review examines the epidemiology of leptospirosis in the UK, over the period 2006-10, the clinical features, diagnostic techniques and treatment. PMID:22843698

  12. Finding a VOICE for UK clinical pharmacology.

    PubMed

    Aronson, Jeffrey K

    2012-06-01

    At a James Black Conference held in Oxford on 20-22 June 2011, a group of senior clinical pharmacologists and their junior colleagues, other medical specialists, and pharmacists discussed an agenda for UK clinical pharmacology for the next 5 years, addressing the following broad questions. How should UK clinical pharmacology be further developed and delivered as a discipline in universities, the NHS, pharmaceutical companies, and regulatory authorities? How should teaching and training in UK clinical pharmacology and therapeutics be delivered and assessed? What topics should be priorities for research in UK academic clinical pharmacology? How should clinical pharmacology contribute to UK drugs policy? How should pharmacology and clinical pharmacology be further integrated, to the benefit of both? Numerous recommendations emerged, under the collective acronym VOICE, standing for Visibility, Outreach, Integration, Coverage and Emissaries. VISIBILITY: The visibility of the discipline needs to be increased. This could be done, for example, by increased activities in acute general medicine/toxicology, through activities of Medicines and Therapeutics Committees, participation in grand rounds, teaching and training, and monitoring therapeutic interventions, and by offering bolt-on training for other specialists (for example, short courses, MSc courses, and training programmes). OUTREACH: Methods of increasing outreach include roadshows in schools/medical schools, national special study modules, public education, press coverage, and social marketing. INTEGRATION: Closer collaborations with pharmacologists, clinical pharmacists, other prescribers, and pharmaceutical companies (e.g. through joint training programmes) are desirable. COVERAGE: Attention to neglected areas, such as general practice, paediatrics, obstetrics, geriatrics, anaesthetics, cancer, and immunology. EMISSARIES: Trainees to spread the word. PMID:22360150

    Objectives To assess whether international medical graduates passing the two examinations set by the Professional and Linguistic Assessments Board (PLAB1 and PLAB2) of the General Medical Council (GMC) are equivalent to UK graduates at the end of the first foundation year of medical training (F1), as the GMC requires, and if not, to assess what changes in the PLAB pass marks might produce equivalence. Design Data linkage of GMC PLAB performance data with data from the Royal Colleges of Physicians and the Royal College of General Practitioners on performance of PLAB graduates and UK graduates at the MRCP(UK) and MRCGP examinations. Setting Doctors in training for internal medicine or general practice in the United Kingdom. Participants 7829, 5135, and 4387 PLAB graduates on their first attempt at MRCP(UK) Part 1, Part 2, and PACES assessments from 2001 to 2012 compared with 18 532, 14 094, and 14 376 UK graduates taking the same assessments; 3160 PLAB1 graduates making their first attempt at the MRCGP AKT during 2007-12 compared with 14 235 UK graduates; and 1411 PLAB2 graduates making their first attempt at the MRCGP CSA during 2010-12 compared with 6935 UK graduates. Main outcome measures Performance at MRCP(UK) Part 1, Part 2, and PACES assessments, and MRCGP AKT and CSA assessments in relation to performance on PLAB1 and PLAB2 assessments, as well as to International English Language Testing System (IELTS) scores. MRCP(UK), MRCGP, and PLAB results were analysed as marks relative to the pass mark at the first attempt. Results PLAB1 marks were a valid predictor of MRCP(UK) Part 1, MRCP(UK) Part 2, and MRCGP AKT (r=0.521, 0.390, and 0.490; all P<0.001). PLAB2 marks correlated with MRCP(UK) PACES and MRCGP CSA (r=0.274, 0.321; both P<0.001). PLAB graduates had significantly lower MRCP(UK) and MRCGP assessments (Glass’s Δ=0.94, 0.91, 1.40, 1.01, and 1.82 for MRCP(UK) Part 1, Part 2, and PACES and MRCGP AKT and CSA), and were more likely to fail assessments

    2011-03-01

    The burgeoning population of patients requiring renal replacement therapy contributes a disproportionate strain on National Health Service resources. Although renal transplantation is the preferred treatment modality for patients with established renal failure, achieving both clinical and financial advantages, limitations to organ donation and clinical comorbidities will leave a significant proportion of patients with established renal failure requiring expensive dialysis therapy in the form of either hemodialysis or peritoneal dialysis. An understanding of dialysis economics is essential for both healthcare providers and clinical leaders to establish clinically efficient and cost-effective treatment modalities that maximize service provision. In light of changes to the provision of healthcare funds in the form of "Payment by Results," it is imperative for UK renal units to adopt clinically effective and financially accountable dialysis programs. This article explores the role of dialysis economics and implications for UK renal replacement therapy programs. PMID:21364210

    The unexpected announcement by the UK Chancellor of the Exchequer of a levy on sugar sweetened beverages (SSBs) on the 16 March 2016, should be welcomed by all health professionals. This population based, structural intervention sends a strong message that there is no place for carbonated drinks, neither sugared nor sugar-free, in a healthy diet and the proposed levy has the potential to contribute to both general and dental health. The sugar content of drinks exempt from the proposed sugar levy will still cause tooth decay. Improving the proposed tax could involve a change to a scaled volumetric tax of added sugar with a lower exemption threshold. External influences such as the Common Agricultural Policy and the Transatlantic Trade and Investment Partnership may negate the benefits of the sugar levy unless it is improved. However, the proposed UK sugar tax should be considered as a start in improving the nation's diet.

    The UK Design Council describes Inclusive Design as neither a new genre of design, nor a separate specialism, but as a general approach to designing in which designers ensure that their products and services address the needs of the widest possible audience, irrespective of age or ability. Inclusive Design (also known [in Europe] as Design for All and as Universal Design in the USA) is in essence the inverse of earlier approaches to designing for disabled and elderly people as a sub-set of the population, and an integral part of a more recent international trend towards the integration of older and disabled people in the mainstream of society. This paper describes the development of Inclusive Design in the UK, from its early beginnings, through its subsequent adoption as a topic of academic research, leading to its recent emergence embodied as a framework and toolkit for design.

    2011-01-01

    The authors review the etiology of U.K. military burns in light of increasing hybrid warfare. Analysis of the nature of these injured personnel will provide commanders with the evidence to plan for on-going and future operations. Case notes of all U.K. Armed Forces burn injured patients who were evacuated to the Royal Centre for Defence Medicine were reviewed. Demographics, burn severity, pattern, and mortality details were included. There were 134 U.K. military personnel with burns requiring return to the United Kingdom during 2001-2007. The median age was 27 (20-62) years. Overall, 60% of burns seen were "accidental." Burning waste, misuse or disrespect of fuel, and scalds were the most prevalent noncombat burns. Areas commonly burned were the face, legs, and hands. During 2006-2007 in the two major conflicts, more than 59% (n = 36) of the burned patients evacuated to the United Kingdom were injured during combat. Burns sustained in combat represent 5.8% of all combat casualties and were commonly associated with other injuries. Improvised explosive device, minestrike, and rocket-propelled grenade were common causes. The mean TBSA affected for both groups was 5% (1-70). The majority of combat burn injuries have been small in size. Greater provision of flame retardant equipment and clothing may reduce the extent and number of combat burns in the future. The numbers of noncombat burns are being reduced by good military discipline. PMID:21422938

    2009-04-01

    Anthropogenically aggravated climate change associated with intensive expansion of the global economy has increased the demand for water whilst simultaneously altering natural variability in its distribution, straining water resources unsustainably and inequitably in many parts of the world, increasing drought risk, and encouraging decision-makers to reconsider the security of water supply. Indeed, in the absence of additional resource development, contemporary planning forecasts imply increased water stress across much of the United Kingdom. The regulatory authorities of the UK currently promote increased efficiency of water delivery and consumption combined with a portfolio of financial instruments as a means of reducing water stress, maintaining present levels of consumer service without significant further exploitation of the environment. Despite an increasingly sophisticated understanding of climate change and its effects, significant uncertainty remains in the quantification of its impacts on the water sector, and questions persist as to the effectiveness of such demand management measures compared to that of more traditional infrastructure improvements. Faced with possible futures provided for by detrimentally over-stressed resources, what opportunities remain for future strategic development in the UK? Is there a single national strategy that is both politically and socially acceptable? This ongoing study aims to evolve robust national adaptation strategies by quantifying the projected impacts of climate change across mainland UK using multi-model and perturbed-physics ensembles of projected future climate, encapsulating uncertainties in a scenario-driven integrated water resources model incorporating socio-economic elements.

    We present stable isotopes (C, N, O), C/N measurements and palynology on modern and fossil samples to reconstruct saltmarsh and estuary evolution in central Bahía Samborombón (~35.5°S), Argentina, SW Atlantic, over the last ~8800 years. The integration of these data in a site located ~30 km inland from the modern coastline allow the recognition of the following stages driven by relative sea level and climatic changes: (i) establishment of an estuary between ~8800-7800 cal yr BP and development of middle-to high marsh, followed by (ii) peak marine influence and establishment of a low marsh zone between ~7800-6200 cal yr BP. (iii) Sea-level lowering was underway by ~5050 cal yr BP leading to decreasing in marine influence at ~3100 cal yr BP under evaporative conditions, culminating in (iv) the estuary deterioration and establishment of halophytic vegetation on the Río Salado floodplain between ~3100-1000 cal yr BP surrounded by Pampa grasslands. A sediment core obtained 2 km inland from the present coast shows development of a low marsh at ~1500 cal yr BP under variable tidal influence, shifting to middle-to-high marsh in response to the construction of an artificial channel on AD 1910.

    The aim of this study was to determine the threshold of fracture probability at which interventions became cost-effective in women based on data from the UK. We modelled the effects of an intervention costing pound 350 per year given for 5 years that decreased the risk of all osteoporotic fractures by 35% followed by a waning of effect (offset time) for a further 5 years. Sensitivity analyses included a range of treatment duration (3-10 years), intervention costs (pound 300-400/year) and offset times (0-15 years). Data on costs and risks were from the UK. Costs included direct costs, but excluded indirect costs due to morbidity. A threshold for cost-effectiveness of pound 30,000/QALY gained was used. With the base case ( pound 350 per year; 35% efficacy) treatment in women was cost-effective with a 10-year hip fracture probability that ranged from 1.1% at the age of 50 years to 9.0% at the age of 85 years. Intervention thresholds were sensitive to the assumed costs and offset time. The exclusion of osteoporotic fractures other than hip fracture significantly increased the cost-effectiveness ratio because of the substantial morbidity from such other fractures, particularly at younger ages. Cost-effective scenarios were found for women at the threshold for osteoporosis from the age of 60 years. Treatment of established osteoporosis was cost-effective irrespective of age. We conclude that the inclusion of all osteoporotic fractures has a marked effect on intervention thresholds, that these vary with age and that available treatments can be targeted cost-effectively to individuals from the UK at moderately increased fracture risk.

  10. Clinical experience of lymphangioleiomyomatosis in the UK

    PubMed Central

    Johnson, S; Tattersfield, A

    2000-01-01

    BACKGROUND—Lymphangioleiomyomatosis is a rare lung disease that affects only women. No controlled trials of management have been performed and, until such data are available, management must be based on clinical experience. This study provides data on the natural history of lymphangioleiomyomatosis in the UK and compares this with experience from other centres.
METHODS—We tried to identify all cases of lymphangioleiomyomatosis in the UK over a five year period by contacting all chest physicians. Cases were confirmed by lung biopsy or history and high resolution computed tomographic (CT) scanning. Details of disease and management were obtained from hospital notes.
RESULTS—The 50 patients who fitted the diagnostic criteria for lymphangioleiomyomatosis had a median age at onset of 35 years (range 22-50). Five presented when postmenopausal (four taking hormone replacement therapy). Pneumothorax and dyspnoea were the most common presenting features. Extrapulmonary presentations included renal angiomyolipomas (3) and lymphangiomyomas (2). Only half the patients were assessed for renal angiomyolipoma and six were identified. Thirty patients had had one or more pneumothoraces, of which two thirds recurred if treated conservatively. Chylous effusions occurred in 11 patients, five requiring surgery. Pregnancy was uncommon once the diagnosis was made (n=7), but was associated with an increase in complications. Half the patients were taking a β agonist and many showed a bronchodilator response in the laboratory. Thirty six patients had received hormone treatment.
CONCLUSIONS—Our UK five year period prevalence was one per 1.1 million population. Since prophylactic interventions are sometimes indicated for renal angiomyolipoma, these data suggest that screening for angiomyolipoma, ideally by CT scanning, may be underused. Patients need to be aware of the increase in complications associated with pregnancy. Recurrence rate of pneumothorax was high in those not

    2009-12-01

    Anthropogenically aggravated climate change associated with intensive expansion of the global economy has increased the demand for water whilst simultaneously altering natural variability in its distribution, straining water resources unsustainably and inequitably in many parts of the world, increasing drought risk, and encouraging decision-makers to reconsider the security of water supply. Indeed, in the absence of additional resource development, contemporary planning forecasts imply increased water stress across much of the United Kingdom. Until recently the regulatory authorities of the UK promoted increased efficiency of water delivery and consumption combined with a portfolio of financial instruments as a means of reducing water stress, maintaining present levels of consumer service without significant further exploitation of the environment. However, despite an increasingly sophisticated understanding of climate change and its effects, significant uncertainty remains in the quantification of its impacts on the water sector, and questions persist as to the effectiveness of such demand management measures compared to that of more traditional infrastructure improvements. Faced with possible futures provided for by detrimentally over-stressed resources, what opportunities remain for future strategic development in the UK? Is there a single national strategy that is both politically and socially acceptable? Do the benefits of national water infrastructure projects outweigh their costs? This ongoing study aims to evolve robust national adaptation strategies by quantifying the projected impacts of climate change across mainland UK using multi-model and perturbed-physics ensembles of projected future climate, encapsulating uncertainties in a scenario-driven integrated water resources model incorporating socio-economic elements.

  12. Well integrity failure in the UK

    Worrall, F.

    2015-12-01

    The aim of this study was to consider the potential legacy of increased onshore, unconventional gas production by examining the integrity of decommissioned, onshore, oil and gas wells in the UK. In the absence of a history of unconventional hydrocarbon exploitation in the UK, conventional onshore sites were considered and an examination of pollution incidents records had suggested that only a small fraction of operational, onshore wells could show integrity failures. A consideration of groundwater and surface water quality monitoring could find no regional impact of historic or current conventional oil and gas exploitation in the UK. As a more direct measure of well legacy this study considered the fugitive emissions of methane from former oil and gas wells onshore in the UK as a measure of well integrity. The survey considered 102 decommissioned (abandoned) wells from 4 different basins that were between 8 and 78 years old; all but one of these wells would be considered as having been decommissioned properly, i.e. wells cut, sealed and buried by soil cover to the extent that the well sites were being used for agriculture. For each well site the soil gas methane was analysed multiple times and assessed relative to a nearby control site of similar land-use and soil type. The results showed that of the 102 wells surveyed, 30% had soil gas CH4 at the soil surface that was significantly greater than their respective control. Conversely, 39% of well sites had significant lower surface soil gas CH4 concentrations than their respective control. We interpret elevated soil gas CH4 concentrations to be the result of well integrity failure, but do not know the source of the gas nor the route to the surface. Where elevated CH4 was detected it appears to have occurred within a decade of the well being decommissioned. The flux of CH4 from wells was 364 ± 677 kg CO2eq/well/yr with a 27% chance that any well would be a net sink of CH4 independent of well age. This flux is low

    Physicists have reacted angrily to plans by one of the UK's leading research councils to slash funding for a number of key national facilities. The Science and Technology Facilities Council (STFC) will cut support for the Diamond light source and make "reductions in facility operations" at the ISIS neutron source and the Central Laser Facility. STFC chief executive Keith Mason blames the cuts on the fall in the value of the pound, which has led to a 15.1% rise in the STFC's subscriptions to CERN and other international facilities from £214.9m last year to £247.3m in 2009-2010.

    The UK's Human Rights Act 1998, which incorporates into that country's law the European Convention on Rights and Freedoms, came into full operation on Oct 2, 2000. The Act imposes duties on public authorities, who must now justify their position if that is in conflict with a Convention right. Four Articles in the Convention are potential flashpoints in respect of health cases, examples being patients' rights to receive expensive life-saving treatment and disciplinary procedures, including those of the General Medical Council and National Health Service trusts.

    Paediatric clinical pharmacology is the scientific study of medicines in children and is a relatively new subspecialty in paediatrics in the UK. Training encompasses both the study of the effectiveness of drugs in children (clinical trials) and aspects of drug toxicity (pharmacovigilance). Ethical issues in relation to clinical trials and also studies of the pharmacokinetics and drug metabolism in children are crucial. Paediatric patients require formulations that young children in particular are able to take. The scientific evidence generated from clinical trials, pharmacokinetic studies and studies of drug toxicity all need to be applied in order to ensure that medicines are used rationally in children.

    Following a request from a Governmental Interdepartmental Group, the Health and Safety Executive undertook a polychlorinated dibenzo-p-dioxin (PCDD) and polychorinated dibenzofuran (PCDF) sampling exercise at several work sites in the UK. An initial survey suggested potential PCDD/F production at metal recycling sites, during cement manufacture, at municipal waste incinerators and landfill sites and during the use of thermal oxygen lances. PCDD/F sampling, using static and personal air samplers, revealed that the highest PCDD/F exposures were found at metal recycling sites, particularly aluminium recycling sites. The reasons for these results and the possible consequential intakes are discussed.

The review, which will be led by physicist Bill Wakeham from Southampton University, was announced late last year by the science minister Ian Pearson after an £80m shortfall in the budget of the Science and Technology Facilities Council (STFC) forced it to pull out of the Gemini telescopes, withdraw from the International Linear Collider (ILC), and cut university grants by 25% in particle physics and astronomy.

The Clover project - a collaboration between Cambridge, Cardiff, Manchester and Oxford universities - was designed to search for the signatures of gravitational waves in the cosmic microwave background (CMB). However, the STFC cancelled the project because constructions costs had risen by 60% to some £7.5m.

  3. Supporting UK adaptation: building services for the next set of UK climate projections

    NASA Astrophysics Data System (ADS)

    2016-04-01

    As part of the Climate Change Act 2008, the UK Government sets out a national adaptation programme to address the risks and opportunities identified in a national climate change risk assessment (CCRA) every five years. The last risk assessment in 2012 was based on the probabilistic projections for the UK published in 2009 (UKCP09). The second risk assessment will also use information from UKCP09 alongside other evidence on climate projections. However, developments in the science of climate projeciton, and evolving user needs (based partly on what has been learnt about the diverse user requirements of the UK adaptation community from the seven years of delivering and managing UKCP09 products, market research and the peer-reviewed literature) suggest now is an appropriate time to update the projections and how they are delivered. A new set of UK climate projections are now being produced to upgrade UKCP09 to reflect the latest developments in climate science, the first phase of which will be delivered in 2018 to support the third CCRA. A major component of the work is the building of a tailored service to support users of the new projections during their development and to involve users in key decisions so that the projections are of most use. We will set out the plan for the new climate projections that seek to address the evolving user need. We will also present a framework which aims to (i) facilitate the dialogue between users, boundary organisations and producers, reflecting their different decision-making roles (ii) produce scientifically robust, user-relevant climate information (iii) provide the building blocks for developing further climate services to support adaptation activities in the UK.

  4. Refugee blues: a UK and European perspective

    PubMed Central

    Turner, Stuart

    2015-01-01

    In this paper, the numbers of refugees travelling to the European Union are set in a global context. It is argued that the increasing restrictions placed on asylum seekers from the 1980s onwards in the UK and the associated culture of deterrence and prohibition have had the perverse effect of supporting the economic market for people smuggling. It appears that these restrictions were initially designed to deter people, most of whom would have been granted humanitarian assistance had they managed to arrive in the UK, so as to prevent them from accessing the decision-making process on asylum. Policy changes concerning travel, benefits, and other pressures on asylum seekers are also considered in the context of deterrence. The problems facing asylum seekers do not end with their arrival in a safe country. The current methods of determining refugee status are alarmingly weak. Indeed there is evidence suggesting that those who are most traumatised before arrival face systematic disadvantage. The focus of this paper is on the United Kingdom but its conclusions apply to most Western European countries. The paper concludes with some tentative suggestions for change. PMID:26514159

    In the UK, as in most other countries in the world, levels of obesity are increasing. According to the Kinsey report, obesity has the second largest public health impact after smoking, and it is inextricably linked to physical inactivity. Since the UK Health and Social Care Act reforms of 2012, there has been a significant restructuring of the National Health Service (NHS). As a consequence, NHS England and the Department of Health have issued new policy guidelines regarding the commissioning of obesity treatment. A 4-tier model of care is now widely accepted and ranges from primary activity, through community weight management and specialist weight management for severe and complex obesity, to bariatric surgery. However, although there are clear care pathways and clinical guidelines for evidence-based practice, there remains no single stakeholder willing to take overall responsibility for obesity care. There is a lack of provision of adequate services characterised by a noticeable 'postcode lottery', and little political will to change the obesogenic environment.

    2015-01-01

    Teaching Fellowships for junior doctors in their second post-graduate (FY2) year should be considered by medical students and junior doctors in UK. FY2 Teaching Fellowships are available in many foundation schools as part of the UK Academic Foundation Programme. Although programme structures differ between schools, they are designed to allow junior trainees to take time out from clinical practice to develop their teaching skills and gain insights into medication education careers. The advantages of an FY2 teaching fellowship include valuable experience of teaching and formal feedback not available to other trainees; the opportunity to further develop your portfolio; further development of the trainee's own knowledge and skills; the stimulation of working with students. Potential drawbacks to be considered are reduced direct clinical contact; reduced salary; difficulty carrying out education research in the allocated time frame; occasional difficulties establishing the teacher-student relationship while the trainee is at a relatively junior level. Experience of medical education as an FY2 trainee provides a helpful stepping stone whether or not the trainee further pursues education as a career, because the teaching skills are transferable to any specialty, and the unique experience enhances the trainee's confidence as a role model for junior colleagues.

  7. Low background screening capability in the UK

    Low background rare event searches in underground laboratories seeking observation of direct dark matter interactions or neutrino-less double beta decay have the potential to profoundly advance our understanding of the physical universe. Successful results from these experiments depend critically on construction from extremely radiologically clean materials and accurate knowledge of subsequent low levels of expected background. The experiments must conduct comprehensive screening campaigns to reduce radioactivity from detector components, and these measurements also inform detailed characterisation and quantification of background sources and their impact, necessary to assign statistical significance to any potential discovery. To provide requisite sensitivity for material screening and characterisation in the UK to support our rare event search activities, we have re-developed our infrastructure to add ultra-low background capability across a range of complementary techniques that collectively allow complete radioactivity measurements. Ultra-low background HPGe and BEGe detectors have been installed at the Boulby Underground Laboratory, itself undergoing substantial facility re-furbishment, to provide high sensitivity gamma spectroscopy in particular for measuring the uranium and thorium decay series products. Dedicated low-activity mass spectrometry instrumentation has been developed at UCL for part per trillion level contaminant identification to complement underground screening with direct U and Th measurements, and meet throughput demands. Finally, radon emanation screening at UCL measures radon background inaccessible to gamma or mass spectrometry techniques. With this new capability the UK is delivering half of the radioactivity screening for the LZ dark matter search experiment.

  8. Assisted reproductive travel: UK patient trajectories.

    PubMed

    Hudson, Nicky; Culley, Lorraine

    2011-11-01

    Media reporting of 'fertility tourism' tends to portray those who travel as a cohesive group, marked by their desperation and/or selfishness and propensity towards morally questionable behaviour. However, to date little has been known about the profile of those leaving the UK for treatment. This paper discusses the first UK-based study of patient assisted reproduction travel that was designed to explore individual travel trajectories. It is argued that existing ways of conceptualizing cross-border reproductive care as 'fertility or reproductive tourism' are in danger of essentializing what the data suggest are diverse, complex and often ambiguous motivations for reproductive travel. The concept of seriality is used to suggest that, whilst 'reproductive tourists' share some characteristics, they also differ in significant ways. This paper argues that, through an examination of the personal landscapes of fertility travel, the diverse processes involved in reproductive travel can be better understood and policymakers can be assisted to avoid what might be regarded as simplistic responses to cross-border reproductive care.

    Excess Winter Mortality is a peak in the population's mortality rate during winter months and is correlated with low outdoor temperatures. Excess Winter Mortality has adverse impacts, including increased demand on health services. The management of resources for such increased demands maybe improved through incorporation of weather forecasting information to advanced warnings. For the UK, prolonged cold periods are associated with easterly advection, and high pressure systems. Characterisation of the synoptic conditions associated with cold periods is important to understand forecast performance. Principal Component Analysis has been used with mean sea level pressure from 35 years of ERA interim reanalysis to capture synoptic variability on a continuous scale. Cold events in the North and South of the UK mainland have been identified as having different synoptic variability using this method. Furthermore extending the Principal Component Analysis to investigate the skill of forecasts has identified systematic under prediction of some cold weather synoptic conditions. Ensemble forecasts are used to quantify the uncertainty associated with these cold weather synoptic conditions. This information maybe be used to improve the value of existing weather warnings.

    Privacy has been and continues to be one of the key challenges of an age devoted to the accumulation, processing, and mining of electronic information. In particular, privacy of healthcare-related information is seen as a key issue as health organizations move towards the electronic provision of services. The aim of the research detailed in this paper has been to analyse privacy policies on popular UK healthcare-related websites to determine the extent to which consumer privacy is protected. The author has combined approaches (such as approaches focused on usability, policy content, and policy quality) used in studies by other researchers on e-commerce and US healthcare websites to provide a comprehensive analysis of UK healthcare privacy policies. The author identifies a wide range of issues related to the protection of consumer privacy through his research analysis using quantitative results. The main outcomes from the author's research are that only 61% of healthcare-related websites in their sample group posted privacy policies. In addition, most of the posted privacy policies had poor readability standards and included a variety of privacy vulnerability statements. Overall, the author's findings represent significant current issues in relation to healthcare information protection on the Internet. The hope is that raising awareness of these results will drive forward changes in the industry, similar to those experienced with information quality.

    The Norwegian Water Resources and Energy Directorate (NVE) and the British Geological Survey (BGS) compile daily landslide hazard assessments (DLHA) in their respective countries. NVE DLHA has been operational since 2013 and provides national daily assessments based on quantitative thresholds related to daily hydro-meteorological forecasts coupled with qualitative expert analysis of these forecasts. The BGS DLHA has been operational since 2012 and this is predominantly based on expert evaluation of antecedent hydro-meteorological conditions and triggering rainfall across Great Britain (GB). In both cases, the hydro-meteorological evaluation is coupled with observations derived from proprietary datasets on landslide events and landslide potential in order to specify, and limit, the spatial extent of the potentially impacted area. However, the DLHA are strongly driven by hydro-meteorological forecasts. In December 2015, a large extra-tropical cyclone developed over the Atlantic and delivered record-breaking precipitation over parts of the UK and Norway. The meteorological services started naming these events to enhance public uptake and awareness and the storms were named as Desmond (the 4th large storm in 2015/16 in the UK) and Synne (the 5th storm in 2015 in Norway). Desmond arrived in earnest on the 5th of December and brought intense precipitation and strong winds over a 48-hour period. In Cumbria (NW-England) record precipitation was measured (341.4 mm in 24-hour at Honister Pass which is more than twice the monthly average), with 48-hour accumulations exceeding 400 mm. Synne arrived shortly after in Norway and was also characterised by excessive rainfall of 140 mm in 24-hour, 236 mm in 48-hour and 299 mm in 72-hour at Maudal, SW-Norway. Both organisations managed to issue appropriate advance warnings, operating individually. In Norway, warnings were issued some 2 days in advance with a yellow level communicated on Friday 4th and an orange warning the 5th and 6

The current model of pharmacovigilance and its associated tools have been developed in relation to synthetic drugs, and applying these methods to monitoring the safety of herbal medicines presents unique challenges in addition to those described for conventional medicines. Several problems relate to the ways in which herbal medicines are named, perceived, sourced, and utilised. Other important challenges arise from the current regulatory framework for herbal medicines in the UK. In the UK at present, the Committee on Safety of Medicines/Medicines and Healthcare products Regulatory Agency's (CSM/MHRA) 'yellow card' scheme for adverse drug reaction (ADR) reporting is the main method of monitoring the safety of herbal medicines. Despite recent initiatives to stimulate reporting of suspected ADRs associated with herbal medicines, such as extending the scheme to unlicensed herbal products, and including community pharmacists as recognised reporters, numbers of herbal ADR reports received by the CSM/MHRA remain relatively low. Under-reporting, an inevitable and important limitation of spontaneous reporting schemes, is likely to be significant for herbal medicines, since users typically do not seek professional advice about their use of such products, or report if they experience adverse effects. The herbal sector in the UK has initiated various spontaneous reporting schemes, based on the yellow card scheme, but targeted mainly at herbal-medicine practitioners. It is important that these schemes have a link with the CSM/MHRA so that potential signals are not missed. Several other tools used in pharmacovigilance of conventional medicines, such as prescription-event monitoring, and the use of computerised health-record databases, currently are of no use for evaluating the safety of herbal and other non-prescription medicines.

    2016-02-01

    Ongoing serious breaches in medical professionalism might be avoided if UK doctors rethink their approach to law. UK medical education has a role in creating a climate of change by re-examining how law is taught to medical students. Adopting a more insightful approach in the UK to the impact of The Human Rights Act and learning to manipulate legal concepts, such as conflict of interest, need to be taught to medical students now if UK doctors are to manage complex decision-making in the NHS of the future. The literature is reviewed from a unique personal perspective of a doctor and lawyer, and practical proposals for developing medical education in law in the UK are suggested.

  20. Challenges for academic accreditation: the UK experience

    Shearman, Richard; Seddon, Deborah

    2010-08-01

    Several factors (government policy, demographic trends, employer pressure) are leading to new forms of degree programmes in UK universities. The government is strongly encouraging engagement between universities and employers. Work-based learning is increasingly found in first and second cycle programmes, along with modules designed by employers and increasing use of distance learning. Engineering faculties are playing a leading part in these developments, and the Engineering Council, the engineering professional bodies and some universities are collaborating to develop work-based learning programmes as a pathway to professional qualification. While potentially beneficial to the engineering profession, these developments pose a challenge to traditional approaches to programme accreditation. This paper explores how this system deals with these challenges and highlights the issues that will have to be addressed to ensure that the system can cope effectively with change, especially the development of individually tailored, work-based second cycle programmes, while maintaining appropriate standards and international confidence.

  1. Atomic Weapons Establishment, Aldermaston UK site overview

    Elliott, R.A.

    1990-11-01

    The UK Nuclear Weapons Industry has at its core the Atomic Weapons Establishments at Aldermaston, Burghfield, Cardiff and Foulness all of which are part of the Ministry of Defense (MOD). The paper illustrates the upper echelons of the MOD and shows the structure within Aldermaston. The Superintendent Quality Management has three sections: Inspection, Quality Assurance and Development, the latter of which contains the Robotics Section. The locations of the establishments are shown. Remote handling and automation of production procedures distance the operator from hazardous materials in the following areas: (1) The glovebox environment where radioactive and hygroscopic materials are machined and measured; (2) The remote cell environment for machining and assembly of explosive and radioactive materials; and (3) decommissioning activities in the waste management group at Aldermaston. The robotics section provides an advisory service to all sites but may also be tasked internally by other sections within the Superintendency.

  2. The UK Nitrate Time Bomb (Invited)

    The developed world has benefitted enormously from the intensification of agriculture and the increased availability and use of synthetic fertilizers during the last century. However there has also been unintended adverse impact on the natural environment (water and ecosystems) with nitrate the most significant cause of water pollution and ecosystem damage . Many countries have introduced controls on nitrate, e.g. the European Union's Water Framework and Nitrate Directives, but despite this are continuing to see a serious decline in water quality. The purpose of our research is to investigate and quantify the importance of the unsaturated (vadose) zone pathway and groundwater in contributing to the decline. Understanding nutrient behaviour in the sub-surface environment and, in particular, the time lag between action and improvement is critical to effective management and remediation of nutrient pollution. A readily-transferable process-based model has been used to predict temporal loading of nitrate at the water table across the UK. A time-varying nitrate input function has been developed based on nitrate usage since 1925. Depth to the water table has been calculated from groundwater levels based on regional-scale observations in-filled by interpolated river base levels and vertical unsaturated zone velocities estimated from hydrogeological properties and mapping. The model has been validated using the results of more than 300 unsaturated zone nitrate profiles. Results show that for about 60% of the Chalk - the principal aquifer in the UK - peak nitrate input has yet to reach the water table and concentrations will continue to rise over the next 60 years. The implications are hugely significant especially where environmental objectives must be achieved in much shorter timescales. Current environmental and regulatory management strategies rarely take lag times into account and as a result will be poorly informed, leading to inappropriate controls and conflicts

  3. Seasonal UK Drought Forecasting using Statistical Methods

    Richardson, Doug; Fowler, Hayley; Kilsby, Chris; Serinaldi, Francesco

    2016-04-01

    In the UK drought is a recurrent feature of climate with potentially large impacts on public water supply. Water companies' ability to mitigate the impacts of drought by managing diminishing availability depends on forward planning and it would be extremely valuable to improve forecasts of drought on monthly to seasonal time scales. By focusing on statistical forecasting methods, this research aims to provide techniques that are simpler, faster and computationally cheaper than physically based models. In general, statistical forecasting is done by relating the variable of interest (some hydro-meteorological variable such as rainfall or streamflow, or a drought index) to one or more predictors via some formal dependence. These predictors are generally antecedent values of the response variable or external factors such as teleconnections. A candidate model is Generalised Additive Models for Location, Scale and Shape parameters (GAMLSS). GAMLSS is a very flexible class allowing for more general distribution functions (e.g. highly skewed and/or kurtotic distributions) and the modelling of not just the location parameter but also the scale and shape parameters. Additionally GAMLSS permits the forecasting of an entire distribution, allowing the output to be assessed in probabilistic terms rather than simply the mean and confidence intervals. Exploratory analysis of the relationship between long-memory processes (e.g. large-scale atmospheric circulation patterns, sea surface temperatures and soil moisture content) and drought should result in the identification of suitable predictors to be included in the forecasting model, and further our understanding of the drivers of UK drought.

  4. Multiple-camera tracking: UK government requirements

    Hosmer, Paul

    2007-10-01

    The Imagery Library for Intelligent Detection Systems (i-LIDS) is the UK government's new standard for Video Based Detection Systems (VBDS). The standard was launched in November 2006 and evaluations against it began in July 2007. With the first four i-LIDS scenarios completed, the Home Office Scientific development Branch (HOSDB) are looking toward the future of intelligent vision in the security surveillance market by adding a fifth scenario to the standard. The fifth i-LIDS scenario will concentrate on the development, testing and evaluation of systems for the tracking of people across multiple cameras. HOSDB and the Centre for the Protection of National Infrastructure (CPNI) identified a requirement to track targets across a network of CCTV cameras using both live and post event imagery. The Detection and Vision Systems group at HOSDB were asked to determine the current state of the market and develop an in-depth Operational Requirement (OR) based on government end user requirements. Using this OR the i-LIDS team will develop a full i-LIDS scenario to aid the machine vision community in its development of multi-camera tracking systems. By defining a requirement for multi-camera tracking and building this into the i-LIDS standard the UK government will provide a widely available tool that developers can use to help them turn theory and conceptual demonstrators into front line application. This paper will briefly describe the i-LIDS project and then detail the work conducted in building the new tracking aspect of the standard.

  5. Oxidative ratio (OR) of UK peats

    NASA Astrophysics Data System (ADS)

    2012-04-01

    The oxidative ratio (OR) is the amount of CO2 sequestered in the terrestrial biosphere for each mol of O2 produced. The OR governs the effectiveness of a terrestrial biome to mitigate the impact of anthropogenic CO2 emissions and it has been used to calculate the balance of terrestrial and oceanic carbon sinks across the globe. However, few studies have investigated the controls of the variability in OR. What factors affect OR - climate? Soil type? Vegetation type? N deposition? Land use? Land use change? Small shifts in OR could have important implications in the global partitioning of CO2 between the atmosphere, biosphere, and oceans. This study looks at peat soils (Histosols) from a series of sites representing a climatic transect across the UK. Duplicate peat cores were taken, along with samples of above-ground vegetation and litter, from sites in northern Scotland (Forsinard), southern Scotland (Auchencorth), northern England (Moor House; Thorne Moor) through the Welsh borders (Whixhall Moss) and Somerset levels (Westhay Moor) to Dartmoor and Bodmin Moor in the south west of England. Sub-samples of the cores were analysed for their CHNO concentrations using a Costech ECS 4010 Elemental combustion system. Using the method of Masiello et al. (2008), OR values could be calculated from these elemental concentrations. Initial results show that OR values of UK peats varied between 0.94 and 1.1 with a median value of 1.05 which similar to the median value of World soils but the range is at the more reduced end. There was significant variation between peat cores, even between peat cores on the same site and the peat showed significant reduction in OR with depth in the core.

  6. SSTL UK-DMC SLIM-6 data quality assessment

    2009-01-01

    Satellite data from the Surrey Satellite Technology Limited (SSTL) United Kingdom (UK) Disaster Monitoring Constellation (DMC) were assessed for geometric and radiometric quality. The UK-DMC Surrey Linear Imager 6 (SLIM-6) sensor has a 32-m spatial resolution and a ground swath width of 640 km. The UK-DMC SLIM-6 design consists of a three-band imager with green, red, and near-infrared bands that are set to similar bandpass as Landsat bands 2, 3, and 4. The UK-DMC data consisted of imagery registered to Landsat orthorectified imagery produced from the GeoCover program. Relief displacements within the UK-DMC SLIM-6 imagery were accounted for by using global 1-km digital elevation models available through the Global Land One-km Base Elevation (GLOBE) Project. Positional accuracy and relative band-to-band accuracy were measured. Positional accuracy of the UK-DMC SLIM-6 imagery was assessed by measuring the imagery against digital orthophoto quadrangles (DOQs), which are designed to meet national map accuracy standards at 1:24000 scales; this corresponds to a horizontal root-mean-square accuracy of about 6 m. The UK-DMC SLIM-6 images were typically registered to within 1.01.5 pixels to the DOQ mosaic images. Several radiometric artifacts like striping, coherent noise, and flat detector were discovered and studied. Indications are that the SSTL UK-DMC SLIM-6 data have few artifacts and calibration challenges, and these can be adjusted or corrected via calibration and processing algorithms. The cross-calibration of the UK-DMC SLIM-6 and Landsat 7 Enhanced Thematic Mapper Plus was performed using image statistics derived from large common areas observed by the two sensors. ?? 2006 IEEE.

  7. The siting of UK nuclear reactors.

    Grimston, Malcolm; Nuttall, William J; Vaughan, Geoff

    2014-06-01

    Choosing a suitable site for a nuclear power station requires the consideration and balancing of several factors. Some 'physical' site characteristics, such as the local climate and the potential for seismic activity, will be generic to all reactors designs, while others, such as the availability of cooling water, the area of land required and geological conditions capable of sustaining the weight of the reactor and other buildings will to an extent be dependent on the particular design of reactor chosen (or alternatively the reactor design chosen may to an extent be dependent on the characteristics of an available site). However, one particularly interesting tension is a human and demographic one. On the one hand it is beneficial to place nuclear stations close to centres of population, to reduce transmission losses and other costs (including to the local environment) of transporting electricity over large distances from generator to consumer. On the other it is advantageous to place nuclear stations some distance away from such population centres in order to minimise the potential human consequences of a major release of radioactive materials in the (extremely unlikely) event of a major nuclear accident, not only in terms of direct exposure but also concerning the management of emergency planning, notably evacuation.This paper considers the emergence of policies aimed at managing this tension in the UK. In the first phase of nuclear development (roughly speaking 1945-1965) there was a highly cautious attitude, with installations being placed in remote rural locations with very low population density. The second phase (1965-1985) saw a more relaxed approach, allowing the development of AGR nuclear power stations (which with concrete pressure vessels were regarded as significantly safer) closer to population centres (in 'semi-urban' locations, notably at Hartlepool and Heysham). In the third phase (1985-2005) there was very little new nuclear development, Sizewell

  8. Macrophytes: ecosystem engineers in UK urban rivers

    NASA Astrophysics Data System (ADS)

    Gibbs, H.; Gurnell, A.; Heppell, K.; Spencer, K.

    2012-04-01

    Macrophytes act as ecosystem engineers within river channels in that they have the ability to cause geomorphological and ecological change. They induce reductions in flow velocity and associated sediment accumulation, and their system of underground roots and rhizomes also reinforces the accumulated sediment reducing sediment erosion and resuspension and creating habitats. As sediments, particularly finer-grained, store contaminants including metals, this engineering means that in the specific context of urban rivers where sediments are more likely to be contaminated, macrophytes trap and hold contaminated sediments creating a potentially important sink of metals. However, depending on the ability for the macrophyte to reinforce the sediment and reduce erosion and resuspension, there is the potential for the sink to turn in to a source and metals to be released in to the overlying water. This research therefore looks at the ecosystem engineering ability of common macrophytes in UK urban rivers by looking at: (i) the effect upon flow velocity and sediment accumulation of Sparganium erectum (branched bur-reed); (ii) the sediment reinforcement ability of both S. erectum, Typha latifolia (bulrush) and Phalaris arundinacea (reed canary grass); and, (iii) the storage of metals within the sediment, overlying water and the macrophytes. Research was undertaken on the River Blackwater, an urban river in Surrey, UK which has extensive macrophyte growth. Flow velocity measurements and fine sediment depths were recorded both within and outside of dense stands of S. erectum. The uprooting resistance (as an indicator of sediment reinforcement) was measured for three species: S. erectum, T. latifolia and P. arundinacea. Additionally, some preliminary sampling was undertaken of the sediment, overlying water and the macrophytes to determine metal storage. Lower flow velocities and greater volumes of fine sediment were recorded within the stands of S. erectum as opposed to the

    2015-01-15

    The goat industry in the UK has expanded rapidly in recent years, but at present there is only a poor understanding of the prevalence of parasitic diseases in this farming system. Here, a questionnaire survey of 110 goat owners was used to address this issue. Problems with louse infestation in the previous 12 months were reported by 23% of owners and 19% reported mange. Chorioptic mange was the most common form, with 14 of 21 cases. Sarcoptic mage accounted for only 3 cases and demodex and psoroptic mange each made up 2 cases. Only 53 farmers (48%) said that they took preventative measures to protect their animals against ectoparasite infestation; 20 of these relied on macrocyclic lactones (MLs), the most common product specified was ivermectin. Therapeutic treatment was used by all respondents who said that they had experienced ectoparasites, and again ivermectin was the most common treatment. The use of fipronil was specified by 3 respondents, including one commercial meat producer. Four farmers said that they used antibiotics as an ectoparasiticide. This pattern of treatment for ectoparasites, with reliance on MLs, has implications for the inadvertent selection of resistance in endoparasites. The results suggest that ectoparasites are a major problem for many goat owners, both commercial and non-commercial, but that there is a need for better information for the goat producing community about the optimum approaches to parasite prevention and treatment.

    The Large Hadron Collider (LHC) is one of the greatest scientific endeavours to date. The construction of the collider itself and the experiments that collect data from it represent a huge investment, both financially and in terms of human effort, in our hope to understand the way the Universe works at a deeper level. Yet the volumes of data produced are so large that they cannot be analysed at any single computing centre. Instead, the experiments have all adopted distributed computing models based on the LHC Computing Grid. Without the correct functioning of this grid infrastructure the experiments would not be able to understand the data that they have collected. Within the UK, the Grid infrastructure needed by the experiments is provided by the GridPP project. We report on the operations, performance and contributions made to the experiments by the GridPP project during the years of 2010 and 2011--the first two significant years of the running of the LHC.

  12. Dental disease in chinchillas in the UK.

    2001-01-01

    Dental abnormalities are common in chinchillas, although knowledge of the lesions responsible for the clinical signs is incomplete. Animals bred in the UK were examined to gain further knowledge of dental disease in this chinchilla population. Dental abnormalities, particularly those related to tooth elongation, were detected on careful external examination of 35 per cent of apparently healthy chinchillas. Incisor abnormalities were seen on clinical examination in 55 per cent of chinchillas presented because of clinical illness. In all but one case, this occurred secondarily to crown elongation of the cheek teeth or to the absence of opposing teeth, rather than being a primary skeletal problem. Clinical signs commonly attributed to malocclusion, such as ventral mandibular swelling, weight loss, dysphagia, altered chewing pattern and changed food preferences, were not specific to malocclusion, being seen associated with coronal spike formation, root elongation and advanced periodontal lesions. Caries and resorptive lesions rarely caused clinical signs in this population, but were identified during 37 per cent of postmortem examinations. Congenital absence of teeth, skeletal malocclusion and pathological loss of teeth all resulted in significant clinical signs, but were rare. It is concluded that provision of a diet with physical properties more closely matching that of wild chinchillas should improve the dental health of captive animals. PMID:11219817

  13. Shale gas exploration potential in the UK

    NASA Astrophysics Data System (ADS)

    Smith, N.

    2009-04-01

    Shale gas exploration is one of the main new ‘unconventional' hydrocarbon plays and production is now a major contribution to USA's indigenous supply. BGS has begun a study of hydrocarbon exploration and other data to assess the potential in the UK. Key shale characteristics have been identified in the USA, including gas window maturity and high total organic carbon (TOC) content. Existing gasfields and discoveries containing migrated gas in conventional reservoirs are the obvious starting points. These prove gas has been generated. Discovering the nearby source rocks, which charged them, involves analysing the gas compositions and their carbon isotope characteristics, as well as delving into past exploration and well completion reports. Also used are parameters more widely available which act as surrogates (e.g. radioactivity for TOC). The main targets are Namurian and Dinantian black shales in northern England, source rocks for the small East Midlands oilfields. Lesser targets occur in southern England near small gasfields and discoveries, probably in Lower Jurassic shales, and possibly Kimmeridge Clay (Upper Jurassic). Their advantage is that natural permeabilities are probably higher than the older formations. Early Palaeozoic shales between the Caledonian and Variscan fold belts may also retain some potential but, unlike the association with the Alum Shale source rock in the Baltic, no gasfields have been discovered. Can shale gas production occur where there are no conventional fields?

  14. Risk factors for UK Plasmodium falciparum cases

    PubMed Central

    2014-01-01

    Background An increasing proportion of malaria cases diagnosed in UK residents with a history of travel to malaria endemic areas are due to Plasmodium falciparum. Methods In order to identify travellers at most risk of acquiring malaria a proportional hazards model was used to estimate the risk of acquiring malaria stratified by purpose of travel and age whilst adjusting for entomological inoculation rate (EIR) and duration of stay in endemic countries. Results Travellers visiting friends and relatives and business travellers were found to have significantly higher hazard of acquiring malaria (adjusted hazard ratio (HR) relative to that of holiday makers 7.4, 95% CI 6.4–8.5, p < 0. 0001 and HR 3.4, 95% CI 2.9-3.8, p < 0. 0001, respectively). All age-groups were at lower risk than children aged 0–15 years. Conclusions These estimates of the increased risk for business travellers and those visiting friends and relatives should be used to inform programmes to improve awareness of the risks of malaria when travelling.

    2015-11-13

    Hookworm-related cutaneous larva migrans (HrCLM) is a skin disease caused by infection with the larvae of animal hookworms. With conditions for infection more favourable in tropical climates, HrCLM in the UK is classically diagnosed in the returning traveller. We present two cases of clinically diagnosed UK-acquired HrCLM from a district general hospital in the south of England. A 68-year-old woman presented with a pruritic serpiginous tract on the right hand. She was a keen gardener and had been handling compost. A 50-year-old man, a long distance runner, presented with a similar lesion on the dorsum of his foot. Both patients were treated with a single dose of albendazole. These cases may represent an emerging infection in the UK. In the absence of a suggestive travel history, early recognition followed by efficient access to therapy is vital for treating HrCLM transmitted in the UK.

    The UK Renal Registry is part of the UK Renal Association and provides independent audit and analysis of renal replacement therapy in the UK. The Registry is funded directly by participating renal units through an annual fee per patient registered. The Registry is now collecting data on incidence and prevalence from 100% of UK renal units, with the five remaining non-linked sites in England providing summary data. Maintaining and enhancing Registry functionality will be an important touchstone for the Connecting for Health initiative. Collaboration with other formal agencies also promises an exciting prospect for future development. After a long proving period, the means, methods and roles have come together to complete an effective adjunct to clinical activity, planning, research and the performance of the renal community.

    Subjects were shown photographs of UK MPs' faces and asked to judge their political affiliations. Participants were unable to correctly distinguish between Conservative and Labour politicians. However, their responses were used to create computer-generated idealised faces representative of each party, which independent evaluators could correctly identify. These faces give an indication of the mental images we might reference when imagining MPs from the two main UK political parties.

    The UK DECC (Deriving Emissions linked to Climate Change) network monitors the atmospheric concentrations of greenhouse gases to assess the impact of international policies related to climate change. The effects of control measures on greenhouse gases introduced under the Kyoto Protocol are now being observed. Continued monitoring is required to assess the overall success of the Protocol. For over 25 years the UK Government has funded high-frequency measurements of greenhouse gases at Mace Head, a global background measurement station on the west coast of Ireland. These in-situ, high-frequency, high-precision measurements are used to estimate emissions of greenhouse gases across the UK using the inversion methodology InTEM (Inversion Technique for Emission Modelling). InTEM links the Met Office's atmospheric dispersion model, NAME (Numerical Atmospheric dispersion Modelling Environment), with the Mace Head observations and provides independent verification of bottom up (inventory) emission estimates. In 2011 the UK government (Department of Energy and Climate Change) funded the establishment and integration of three new tall tower measurements stations in the UK, to allow enhanced resolution emission estimates with decreased uncertainty to be produced using InTEM. The new network became operational in 2012. All three additional stations provide ultra high-frequency (1 sec) data of CO2 and CH4 using the Picarro© Cavity Ring Down Spectrometer and high frequency (10 min) measurements of N2O and SF6 from custom built sample modules with GC-ECD. We will present the new UK measurement network in detail along with the new inversion results highlighting the enhanced resolution in regional emission maps for the UK. These results are presented to the UK government annually and provide independent verification of the emission estimates of radiatively active trace gases. The results are compared to the bottom up inventory emission estimates as submitted to the UNFCCC.

    Concentrations of bromine and iodine were analysed in samples from the 1997 UK Total Diet Study (TDS) using ICP-MS. The data has been used to estimate dietary exposures of UK consumers to these elements from the typical UK diet. Samples for the 20 TDS food groups were obtained from 20 towns in the UK in 1997 and analysed in 1998/99 for total bromine and total iodine concentrations. These samples were also analysed for 12 other elements. The UK regulatory authority had considered iodine recently, but had not considered bromine before. This survey provides up-to-data baseline data for those two elements. Iodine concentrations are similar to those found in recent surveys. Levels of bromine were consistent with previous data where available. Dietary exposures to bromine and iodine were calculated to see if there were any risks to health from the levels of these elements found in the UK diet. The estimated population average exposure to iodine was 0.25 mg d-1, which is within the range of previous estimates (1995, 0.21 mg d-1; 1991, 0.17 mg d-1; 1985, 0.28 mg d-1). The estimated population average exposure to bromine was 3.6 mg d-1.

    Estimates of secondary production ( P/ B ratio and total production) by macrobenthic communities across the UK continental shelf are presented. Values for individual sampling stations varied from 0.21 to 4.1 y - 1 for community P/ B and 3.1 to 897.2 kJ m - 2 y - 1 for total production. Such data fills an important gap pertaining to our understanding of the spatial variation in production estimates for this region. Benthic production estimates varied primarily at small (inter-station) scales (24 nm), although larger-scale differences were observed. In general, the highest production estimates were exhibited by benthic communities in Cardigan Bay (Irish Sea) and East English Channel, while the lowest estimates were observed for the mid- and northern North Sea areas. The former were typified by shallow, gravelly areas of seabed which exhibit high bed tidal stress and do not thermally stratify during the summer months. On average, annelids contribute an overwhelming majority of the total production with different regions varying in the relative contributions from other phyla such as molluscs, crustaceans and echinoderms. Spatial heterogeneity of sediment granulometric variables occurred primarily between stations while those of other variables (e.g., depth, stratification, and tidal bed stress) were more regional. Although a large proportion of the spatial variation in secondary production estimates was not explained by environmental characteristics, the data indicate that such relationships are scale-dependent. Average bed temperature was a significant factor in creating some of the observed differences at large spatial scales. The possible reasons why a larger proportion of the variation in production estimates was not explained by the present study are presented.

    This Paper details the implementation of a 'Decommissioning Trial' to assess the feasibility of decommissioning the redundant pipeline operated by AWE located in Berkshire UK. The paper also presents the tool box of decommissioning techniques that were developed during the decommissioning trial. Constructed in the 1950's and operated until 2005, AWE used a pipeline for the authorised discharge of treated effluent. Now redundant, the pipeline is under a care and surveillance regime awaiting decommissioning. The pipeline is some 18.5 km in length and extends from AWE site to the River Thames. Along its route the pipeline passes along and under several major roads, railway lines and rivers as well as travelling through woodland, agricultural land and residential areas. Currently under care and surveillance AWE is considering a number of options for decommissioning the pipeline. One option is to remove the pipeline. In order to assist option evaluation and assess the feasibility of removing the pipeline a decommissioning trial was undertaken and sections of the pipeline were removed within the AWE site. The objectives of the decommissioning trial were to: - Demonstrate to stakeholders that the pipeline can be removed safely, securely and cleanly - Develop a 'tool box' of methods that could be deployed to remove the pipeline - Replicate the conditions and environments encountered along the route of the pipeline The onsite trial was also designed to replicate the physical prevailing conditions and constraints encountered along the remainder of its route i.e. working along a narrow corridor, working in close proximity to roads, working in proximity to above ground and underground services (e.g. Gas, Water, Electricity). By undertaking the decommissioning trial AWE have successfully demonstrated the pipeline can be decommissioned in a safe, secure and clean manor and have developed a tool box of decommissioning techniques.

    Training in both cervical and non-gynaecological cytology in the UK has never faced a more challenging environment. A national reconfiguration of cervical cytology services has focussed resources on large centres and damaged the traditional links and overlapping roles within non-gynaecological cytology. The UK is now at significant risk of falling behind most European countries in the use of non-gynaecological cytology. The UK currently has five training centres which are approved by the NHS Screening programme for training in cervical cytology; the planned introduction of HPV primary screening and the subsequent dramatic reduction in cervical cytology workload will increase pressure on the remaining training schools. Funding is variable across the country as is the degree of diversification that training schools have undertaken to try to ensure a viable future. It is vital for the future of cytology in the UK that the strong network of training schools remain to ensure the quality of the laboratory service as the UK moves towards HrHPV primary screening. There is no doubt that the training school roles will change and new technology embraced to deliver training fit for the changing role of cytology in healthcare but this will require funding and recognition of the vital role the training centres play in the delivery of high quality training in both cervical and non-gynaecological cytology.

    The UK Polar Network is the UK branch of the IPY Youth Steering Committee, an endorsed IPY Project, and the Association of Polar Early Career Scientists (APECS). We have two aims in the UKPN: (1) to provide a network for early career polar researchers working in the UK and (2) to carry out education and outreach activities in UK schools, science festivals and through our website. The Education and Outreach working group is involved in organising programs for a range of age groups including engaging activities for primary and secondary school children, information packs on careers and gap year ideas to school leavers and undergraduate students. The intention is, as far as possible, to keep these events free through fundraising. In addition we aim to provide funding for UK polar researchers to attend national networking days and international IPY conferences to present their work, and are involved with organising workshops at these events. In addition, our website is being developed to provide discussion boards, careers information for polar researchers, as well as information for the public, photos and blogs from polar researchers in the field.

    2009-12-01

    In all developed countries, once it emerged from the amateur era, Space (and especially rocketry) moved on the public agenda because of its potential significance for both the civil and military policies of governments (coupled with its appetite for new money). In the UK the policy treatment of Space broadly paralleled that in other countries until the post-Empire trauma, the burn-out of the White-Hot Technological revolution of Harold Wilson, and the financial crises of the 1970s exhausted the public appetite for large scale publicly funded projects in high technology. The culmination for Space of these pressures came in 1986-1987 when the UK rejected the emerging international consensus and, almost alone, stayed outside the manned space commitments which developed into the International Space Station. In this paper, Colin Hicks will review the UK political developments which led up to the 1986-1987 decision and how the politics and organisation of UK space activity have developed since then to the point where in 2008 a major government review of the UK involvement in manned space was commissioned.

    2007-01-01

    There are now more than 1,000 constructed wetland systems (CWs) in the UK. The first UK CW database was constructed by Water Research Centre (WRc) and Severn Trent Water Ltd to accompany a book on the design and performance of these systems. In that database, constructed by Gareth Job et al., only 154 beds were listed, most of which were tertiary sewage treatment sites in Severn Trent Water. The Constructed Wetland Association (CWA) was formed in 2000 as a UK water industry body in response to problems caused by unscrupulous constructors. A group of experienced, reputable designers and constructors formed the CWA to bring together best UK practice in order to counteract this problem. The group contains major water companies, designers, constructors, academics, plant growers and operators. They decided that one of the best ways of countering the problem was to assemble a database of design and performance from well-designed systems. After negotiation the CWA group took over responsibility for the database from WRc. The CWA has produced eight updates of the database which now contains information from more than 900 beds. It contains examples of the different variants of CWs in use in the UK. Most of these sites treat sewage/domestic wastewater but the database also includes examples of systems for the treatment of minewater, sludge, landfill leachate, industrial effluents, surface runoff and road runoff. Particular treatment applications are illustrated by case studies which are summary articles describing design, construction and performance. PMID:17802831

    This paper examines how cumulative effects assessment (CEA) has been considered in Strategic Environmental Assessments (SEA) of regional and local plans in a number of case studies in the UK. Initially, the paper presents the legislative and regulatory requirements for assessing cumulative effects in plans and programmes in the UK. The two approaches for assessing plans in the UK, Sustainability Appraisal (SA) and SEA are discussed and in most cases, a combined SA and SEA process is undertaken by Regional and Local Planning Authorities. The strengths and weaknesses of this approach are explored, as well as their usefulness in decision making. There are problems relating to baseline, establishing trends and predicting cumulative effects at the strategic level. The issues in assessing cumulative effects within this SA/SEA framework are discussed and recommendations for improvements are made.

    Statutory Sick Pay, Jobseeker's Allowance, and Employment and Support Allowance are employment-related benefits in the United Kingdom (UK). They correspond to the Injury and Disease Allowance and Unemployment Insurance in Japan. The Government of the UK is determined to reform the benefit system to make it fairer and to improve financial work incentives, using the slogan "Welfare to Work". Against this background, the government of the UK united some non-contributory benefits into a new "Universal Credit" scheme, which started in April 2013. The labor policy was also reformed to improve work incentives, for example by abolishing the Flexible New Deal program and uniting all the "Welfare to Work" policies into the "Work Programme". These reforms are useful for reconsidering the labor and employment-related policy and benefit system of Japan. PMID:24334698

    The ever-growing population of the UK has resulted in increasing demands on its healthcare service. Changes have been introduced in the UK medical training system to avoid loss of training time and make it more focused and productive. Modernizing medical careers (MMC) was introduced in 2005. This promised to reduce the training period for a safe trauma specialist, in trauma and orthopedics, to 10 years. At around the same time, the European Working Time Directive (EWTD) was introduced to reduce the working hours for junior doctors in training, to improve patient safety and also work-life balance of junior doctors. Introduction of the assessment tools from Orthopedic Competency assessment project (OCAP) will help tailor the training according to the needs of the trainee. The aim of this article is to review the changes in the UK orthopedic surgical training over the past two decades.

    The aim of the study was to analyze the saturated fatty acid (SFA) and trans-fatty acid (TFA) contents of popular takeaway foods in the UK (including English, pizza, Chinese, Indian and kebab cuisine). Samples of meals were analyzed by an accredited public analyst laboratory for SFA and TFA. The meals were highly variable for SFA and TFA. English and Pizza meals had the highest median amount of SFA with 35.7 g/meal; Kebab meals were high in TFA with up to 5.2 g/meal. When compared to UK dietary reference values, some meals exceeded SFA and TFA recommendations from just one meal. Takeaway food would be an obvious target to reduce SFA and TFA contents and increase the potential of meeting UK recommendations. Strategies such as reformulation and smaller takeaway portion sizes warrant investigation. PMID:26911372

    The increasing complexity of many restorative procedures often involves articulation of study and working casts to ensure accurate fabrication of restorations. Correct selection and use of articulators can be crucial to successful restoration. The aim of this paper is to determine which articulators are recommended for various restorative procedures in UK dental schools, for use by undergraduate students. A questionnaire-based study of all UK dental schools was carried out, with a 100% response rate. Recommended articulator application for specified procedures was established from the literature and questionnaire results were compared with this. The results indicated that dental schools in the UK generally teach appropriate articulator use for most procedures. However, there are some limited areas of what may be argued to be inappropriate recommendation in some establishments.

    The United Kingdom (UK) and Republic of Ireland (ROI) hospital systems are dependent on junior doctors for their functionality however it is increasingly difficult to recruit UK/ROI trained doctors to fill these posts. Directive 2005/36/EC, which came into force in 2007, is the principal European legislation on the recognition of equivalence of professional qualifications across Europe. European trained doctors are therefore attractive candidates for junior doctor posts. However, although their training is recognised as equivalent by the Irish Medical Council (IMC) and General Medical Council (GMC) they are not being appointed to equivalent posts by the Health Service Executive (HSE) or National Health Service (NHS). With the influence of European Union (EU) centralisation, modification of UK/ROI consultant grade is imminent, possibly to pyramidal structure of the Continental European model with clearer lines of corporate responsibility.

    Following the impacts of the Eyjafjallajokull eruption in 2010, two types of volcanic eruption have been added to the UK Government's National Risk Register for Civil Emergencies. One of these, a large gas-rich volcanic eruption, was identified as a high impact natural hazard, one of the three highest priority natural hazards faced by the UK. This eruption scenario is typified by the Laki eruption in Iceland in 1783-1784. The Civil Contingency Secretariat (CCS) of the UK's Cabinet Office, responsible for Civil Protection in the UK, has since been working on quantifying the risk and better understanding its potential impacts. This involves cross-cutting work across UK Government departments and the wider scientific community in order to identify the capabilities needed to respond to an effusive eruption, to exercise the response and develop increased resilience where possible. As part of its current work, CCS has been working closely with the UK Met Office and other UK agencies and academics (represented by the co-authors and others) to generate and assess the impacts of a 'reasonable worst case scenario', which can be used for decision making and preparation in advance of an eruption. Information from the literature and the findings of an expert elicitation have been synthesised to determine appropriate eruption source term parameters and associated uncertainties. This scenario is then being used to create a limited ensemble of model simulations of the dispersion and chemical conversion of the emissions of volcanic gases during such an eruption. The UK Met Office's NAME Lagrangian dispersion model and the Centre for Ecology and Hydrology's EMEP4UK Eulerian model are both being used. Modelling outputs will address the likelihood of near-surface concentrations of sulphur and halogen species being above specified health thresholds. Concentrations at aviation relevant altitudes will also be evaluated, as well as the effects of acid deposition of volcanic species on

    2016-01-01

    Background Occupational health nurses (OHNs) play a pivotal role in the delivery of occupational health (OH) services. Specific competency guidance has been developed in a number of countries, including the UK. While it is acknowledged that UK OHN practice has evolved in recent years, there has been no formal research to capture these developments to ensure that training and curricula remain up-to-date and reflect current practice. Aims To identify current priorities among UK OHNs of the competencies required for OH practice. Methods A modified Delphi study undertaken among representative OHN networks in the UK. This formed part of a larger study including UK and international occupational physicians. The study was conducted in two rounds using a questionnaire based on available guidance on training competencies for OH practice, the published literature, expert panel reviews and conference discussions. Results Consensus among OHNs was high with 7 out of the 12 domains scoring 100% in rating. ‘Good clinical care’ was the principal domain ranked most important, followed by ‘general principles of assessment & management of occupational hazards to health’. ‘Research methods’ and ‘teaching & educational supervision’ were considered least important. Conclusions This study has established UK OHNs’ current priorities on the competencies required for OH practice. The timing of this paper is opportune with the formal launch of the Faculty of Occupational Health Nursing planned in 2018 and should inform the development of competency requirements as part of the Faculty’s goals for standard setting in OHN education and training.

  20. Characterising freeze in the UK: applications for the insurance industry

    The UK winters of 2009-2010 and 2010-2011 were characterised by prolonged and widespread low temperatures. This was challenging for the UK insurance industry and organisations such as the emergency services, the Highways Agency and British Gas who had to manage the extra demands that resulted. In the 6-day period running to Christmas Eve 2010, British Gas reported 100,000 boiler repair call-outs, whilst those 190,000 homes and businesses left with frozen and subsequently burst pipes contributed to the ABI's estimated £ 900 million in insured losses for December 2010 alone; the highest payout by the industry for damages associated with cold weather. Unfortunately, the severity of these winters made the difference between profit and loss for some primary UK insurance companies. To enable better pricing of premiums in the future, insurance companies are looking to understand the potential risk from cold waves at a local, postcode-level, whilst reinsurance firms seek to determine the accumulated loss across the UK associated with spatially coherent events. Other industry sectors also strive to improve their understanding of weather extremes for planning and management. Underpinning this is the need to statistically characterise the physical hazard. Aimed primarily at the re/insurance industry, we have applied an established methodology for developing statistical event sets and applied this to generate a UK freeze event set. An event set provides a stochastic set of several thousand events over 10's of 1000's of years and is typically applied within probabilistic catastrophe models. Our method applies extreme value theory and dependence modelling to explain low-temperature relationships across the UK and over time using historical records. The resulting event set represents the spatial and temporal dependence of cold waves in the UK and is modelled against household factors that increase the vulnerability to freezing conditions, such as property type, age and condition

  1. Maternal near-miss case reviews: the UK approach.

    PubMed

    Knight, M; Lewis, G; Acosta, C D; Kurinczuk, J J

    2014-09-01

    The UK has a well-established programme of Confidential Enquiries into Maternal Deaths and a national system for research into near-miss maternal morbidities, the UK Obstetric Surveillance System. The addition of a programme of near-miss case reviews, the Confidential Enquiries into Maternal Morbidity, permits a complete examination of the incidence, risk factors, care and outcomes of the severest complications in pregnancy, and enables the lessons learnt to improve future care to be identified more quickly. This in turn allows for more rapid inclusion of recommendations into national guidance and hence the potential of better health for both women and babies.

  2. Food irradiation in the UK and the European Directive

    2000-03-01

    Food irradiation in the UK has been authorised since the early 1990s. In principle it is possible to irradiate a wide range of foods for a variety of purposes. In practice food irradiation is virtually non-existent. The structure of food retailing in the UK, a continual stream of food safety scares and a developing public 'crisis of confidence' in the food producer/supply chain have combined to make the future for food irradiation look bleak. The new European Directive on Food Irradiation is unlikely to alter this outlook.

  3. The UK National Flap Registry (UKNFR): A National Database for all pedicled and free flaps in the UK.

    Hazari, Anita; Walton, Peter

    2015-12-01

    The UK National Flap Registry (UKNFR) is a cross-speciality National Clinical Audit with participation by the British Association of Plastic Reconstructive and Aesthetic Surgeons (BAPRAS), British Association of Head and Neck Oncologists (BAHNO), British Association of Oral and Maxillofacial Surgeons (BAOMS) and Association of Breast Surgery (ABS). The aim of UKNFR is to collect information about all major pedicled and free flap operations carried out in the UK and through that, assess the quality of care we provide for patients. This audit will allow appropriate comparison of clinical performance with national standards and provide useful data on changing trends. Participation in audit is integral to appraisal and revalidation in the UK. PMID:26617340

Routledge (University of Leeds, UK), J. Thomas Sanderson (Utrecht University, The Netherlands) and Kirk T. Semple (Lancaster University, UK) The effects of many environmental exposures to either single contaminants or to mixtures still remain to be properly assessed in ecotoxicological and human toxicological settings. Such assessments need to be carried out using relevant biological assays. On a mechanistic basis, future studies need to be able to extrapolate exposure to disease risk. It is envisaged that such an approach would lead to the development of appropriate strategies to either reduce exposures or to initiate preventative measures in susceptible individuals or populations. To mark the opening of a new Institute, the Lancaster Environmental Centre, an environmental health workshop was held over 2 days (9-10 September 2003) at Lancaster University, UK. The fate, behaviour and movement of chemicals in the environment, together with environmental exposures and human health, biomarkers of such exposures, hormone-like compounds and appropriate genetic toxicology methodologies, were discussed.

    We evaluated the impact of shoreline dynamics on fringing vegetation density at mid- and low-marsh elevations at a high-energy site in the northern Gulf of Mexico. Particularly, we selected eight unprotected shoreline stretches (75 m each) at a historically eroding site and measured their inter-annual lateral movement rate using the DSAS method for three consecutive years. We observed high inter-annual variability of shoreline movement within the selected stretches. Specifically, shorelines retrograded (eroded) in year 1 and year 3, whereas, in year 2, shorelines advanced seaward. Despite shoreline advancement in year 2, an overall net erosion was recorded during the survey period. Additionally, vegetation density generally declined at both elevations during the survey period; however, probably due to their immediate proximity with lateral erosion agents (e.g., waves, currents), marsh grasses at low-elevation exhibited abrupt reduction in density, more so than grasses at mid elevation. Finally, contrary to our hypothesis, despite shoreline advancement, vegetation density did not increase correspondingly in year 2 probably due to a lag in response from biota. More studies in other coastal systems may advance our knowledge of marsh edge systems; however, we consider our results could be beneficial to resource managers in preparing protection plans for coastal wetlands against chronic stressors such as lateral erosion.

    Ugochukwu, Nnadozie

    This research aims to provide sufficient insight into the lack of sustainable domestic properties in the UK. The paper reviewed relevant theories of sustainability, with respect to energy performance and environmental friendliness of the built environment. The research also studied the efforts made by the UK Government and other Stakeholders to ensure availability of sustainable domestic properties in the UK, by introducing the Code for Sustainable Homes. The research identified constraints that cause the lack of sustainable domestic properties in the UK, they are: The extra costs associated with building homes to sustainable standards, flexible government legislation, lack of information of the benefits of owning a home built to sustainable standards, and lack of community participation in the formulation of sustainable policies. Recommendations for the availability of more homes built to sustainable standards include the need for mandatory government legislation, making the formulation of policies more participatory amongst the communities where they will be implemented, creating public awareness about the benefits of owning a home built to sustainable standards and the fact that the costs associated with owning such a home is recoverable through savings made in energy costs.

    India and UK have had a long history together, since the times of the British Raj. Most of what Indian psychiatry is today, finds its roots in ancient Indian texts and medicine systems as much as it is influenced by the European system. Psychiatric research in India is growing. It is being influenced by research in the UK and Europe and is influencing them at the same time. In addition to the sharing of ideas and the know-how, there has also been a good amount of sharing of mental health professionals and research samples in the form of immigrants from India to the UK. The Indian mental health professionals based in UK have done a good amount of research with a focus on these Indian immigrants, giving an insight into cross-cultural aspects of some major psychiatric disorders. This article discusses the impact that research in these countries has had on each other and the contributions that have resulted from it. PMID:21836716

    The UK Solar System Data Centre (UKSSDC) has been working to improve access to its extensive holdings of historical ionospheric data. In our archive, ionospheric data from 200 stations worldwide (1930s-present), such as ionograms and scaled ionospheric parameters (e.g., foF2, fmin, h'F2), is held on both digital and physical media. From the 1990s these data sets are available in digital form and can be downloaded from our web-interface. Thanks to a Natural Environment Research Council grant we are in the process of digitising a selection, 2,200 out of ~27,000, of UK ionosonde film data to be made available via the web interface. It is hoped that more funding will be made available to continue this exercise over the next few years. The UKSSDC also provides real-time ionospheric data retrieval from two RAL Space ionosondes, Chilton and Port Stanley, alongside other European observatories. The UKSSDC is part of RAL Space based at Rutherford Appleton Laboratory with the electronic address: http://www.ukssdc.ac.uk. This is a UK national data archive facility with open data access and can be used by scientists around the globe.

    2009-08-01

    The Sequenced Treatment Alternatives to Relieve Depression (STAR*D) program attempted to determine whether some treatment sequences are better than others in the management of depression. Application of the findings to UK treatment settings is difficult because depression is an inhomogeneous condition and to regard it as a unitary entity, to which a unitary stratagem can be applied, is possibly misguided.

  19. Impacts of Russian biomass burning on UK air quality

    NASA Astrophysics Data System (ADS)

    Witham, Claire; Manning, Alistair

    Unusually high levels of PM 10 were observed in the UK in May 2006 and September 2002. This paper investigates the possible contribution of long-range transport of smoke from widespread agricultural burning and forest fires in western Russia to these air pollution episodes. The Lagrangian dispersion model NAME is run in both forwards and backwards modes to determine the transport and sources of the polluted air masses for the two incidents. Comparison of the model results to satellite data and ground observations from across Europe demonstrates good agreement for both the timing and magnitude of the episodes and suggests that fires in western Russia were the primary cause of both incidents. Secondary contributions to the 2006 episode may have come from European anthropogenic pollution and pollen released in northern Europe. The occurrence and timing of both pollution episodes were strongly controlled by the meteorological situation at the time. Scaling of model results to observations suggests that 0.5-0.7 Mtonnes of biomass per day could have been burnt during periods when winds reaching the UK were from the east. The newly reported 2006 episode means that Russian fires have affected UK air quality at least twice since 2000 and it is suggested that, without changes in current practice, such events are likely to occur again in the future with implications for UK and European air quality.

    Allan, Helen; Westwood, Sue

    2016-05-11

    Aim To conduct a scoping project to identify perceived barriers to UK nurse registration as experienced by internationally educated nurses working as healthcare assistants in the UK. Method Eleven internationally educated nurses working as healthcare assistants in two London hospitals attended two facilitated focus groups. Qualitative thematic analysis was used to analyse the data. Findings Study participants articulated frustration with UK English language testing requirements and a sense of injustice and unfairness relating to: double standards for nurses educated within and outside of the European Union (EU) and European Economic Area (EEA); and what was perceived, by some, as arbitrary English language testing with unnecessarily high standards. Differences among study participants related to issues of competency and accountability regarding English language skills and passing English language skills tests, with many feeling they were playing 'a game' where the rules kept changing. Conclusion Language testing barriers are impeding UK nurse registration for some internationally educated nurses from outside the EU and EEA who, as a result, are working as healthcare assistants. The provision of English language training by employers would improve their prospects of achieving nurse registration.

    2011-06-15

    Highlights: > We characterized the key features of the voluntary UK mobile phone takeback network via a survey. > We identified 3 flows: information; product (handsets and accessories); and incentives. > There has been a significant rise in the number of UK takeback schemes since 1997. > Most returned handsets are low quality; little data exists on quantities of mobile phones collected. > Takeback schemes increasingly divert EoL mobile phones from landfill and enable reuse/recycling. - Abstract: Mobile phones are the most ubiquitous electronic product on the globe. They have relatively short lifecycles and because of their (perceived) in-built obsolescence, discarded mobile phones represent a significant and growing problem with respect to waste electrical and electronic equipment (WEEE). An emerging and increasingly important issue for industry is the shortage of key metals, especially the types of metals found in mobile phones, and hence the primary aim of this timely study was to assess and evaluate the voluntary mobile phone takeback network in the UK. The study has characterised the information, product and incentives flows in the voluntary UK mobile phone takeback network and reviewed the merits and demerits of the incentives offered. A survey of the activities of the voluntary mobile phone takeback schemes was undertaken in 2008 to: identify and evaluate the takeback schemes operating in the UK; determine the target groups from whom handsets are collected; and assess the collection, promotion and advertising methods used by the schemes. In addition, the survey sought to identify and critically evaluate the incentives offered by the takeback schemes, evaluate their ease and convenience of use; and determine the types, qualities and quantities of mobile phones they collect. The study has established that the UK voluntary mobile phone takeback network can be characterised as three distinctive flows: information flow; product flow (handsets and related

    Background The health status and lifestyle of migrants is often poorer than that of the general population of their host countries. The Nepalese represent a relatively small, but growing, immigrant community in the UK, about whom very little is known in term of public health. Therefore, our study examined the health and lifestyle of Nepalese migrants in the UK. Methods A cross-sectional survey of Nepalese migrants in UK was conducted in early 2007 using a postal, self-administered questionnaire in England and Scotland (n = 312), and telephone interviews in Wales (n = 15). The total response rate was 68% (327 out of 480). Data were analyzed to establish whether there are associations between socio-economic and lifestyle factors. A multivariate binary logistic regression was applied to find out independent effect of personal factors on health status. Results The majority of respondents was male (75%), aged between 30 and 45 (66%), married or had a civil partner (83%), had university education (47%) and an annual family income (69%) ranging from £5,035 to £33,300. More than one third (39%) of the respondents have lived in the UK for 1 to 5 years and approximately half (46%) were longer-term residents. Most (95%) were registered with a family doctor, but only 38% with a dentist. A low proportion (14%) of respondents smoked but more than half (61%) consumed alcohol. More than half (57%) did not do regular exercises and nearly one fourth (23%) of respondents rated their health as poor. Self reported 'good' health status of the respondents was independently associated with immigration status and doing regular exercise Conclusion The self reported health status and lifestyle, health seeking behaviour of Nepalese people who are residing in UK appears to be good. However, the overall regular exercise and dentist registration was rather poor. Health promotion, especially aimed at Nepalese migrants could help encourage them to exercise regularly and assist them to register

    It has long been understood that accurate prediction and warning of the impacts of severe weather requires an integrated approach to forecasting. This was well demonstrated in the UK throughout winter 2013/14 when an exceptional run of severe winter storms, often with damaging high winds and intense rainfall led to significant damage from the large waves and storm surge along coastlines, and from saturated soils, high river flows and significant flooding inland. The substantial impacts on individuals, businesses and infrastructure indicate a pressing need to understand better the value that might be delivered through more integrated environmental prediction. To address this need, the Met Office, Centre for Ecology & Hydrology and National Oceanography Centre have begun to develop the foundations of a coupled high resolution probabilistic forecast system for the UK at km-scale. This links together existing model components of the atmosphere, coastal ocean, land surface and hydrology. Our initial focus on a 2-year Prototype project will demonstrate the UK coupled prediction concept in research mode, including an analysis of the winter 2013/14 storms and its impacts. By linking science development to operational collaborations such as the UK Natural Hazards Partnership, we can ensure that science priorities are rooted in user requirements. This presentation will provide an overview of UK environmental prediction activities and an update on progress during the first year of the Prototype project. We will present initial results from the coupled model development and discuss the challenges to realise the potential of integrated regional coupled forecasting for improving predictions and applications.

    2004-08-01

    UK-2A is a potent antifungal antibiotic and its structure is highly similar to that of antimycin A3 (AA). UK-2A and AA inhibit mitochondrial electron transport at complex III. C9-UK-2A, which has been prepared to improve the duration of the antifungal activity of UK-2A, shows durable fungicidal activities against various species of fungi and induces both membrane injury and the generation of cellular reactive oxygen species (ROS) against Rhodotorula mucilaginosa IFO 0001 cells. We found that C9-UK-2A inhibited the vegetative growth of Saccharomyces cerevisiae IFO 0203 cells accompanying cellular ROS generation in Sabouraud dextrose (SD) medium, which contained a fermentable carbon source. The ROS generation was completely restricted by pretreatment with a lipophilic antioxidant alpha-tocopherol. In addition, the pretreatment with the antioxidant protected against the growth inhibition induced by C9-UK-2A. C9-UK-2A also induced ROS generation in isolated mitochondria of the S. cerevisiae cells. The addition of both a complex I inhibitor rotenone and a complex II inhibitor thenoyltrifluoroacetone reduced ROS generation induced by C9-UK-2A in the whole cells and the isolated mitochondria. The addition of the inhibitors of complex III, AA or myxothiazol, or of complex IV, KCN, did not reduce ROS generation. These results suggest that C9-UK-2A induces ROS generation due to the blockade of electron flow at complex III, thereby inhibiting the growth of S. cerevisiae in SD medium. PMID:15515888

  1. Thyroid and iodine nutritional status: a UK perspective.

    PubMed

    Vanderpump, Mark

    2014-12-01

    Iodine is an essential component of the thyroid hormones, which play a crucial role in brain and neurological development. At least one-third of the world's population is estimated to be iodine deficient predominantly in developing countries. Recently concern had also been expressed about the iodine status in industrialised countries such as the UK. A recent survey of the UK iodine status found that that more than two-thirds of schoolgirls aged 14-15 years were iodine deficient due to the reduced milk intake. Maternal iodine deficiency in pregnancy is correlated with cognitive outcomes such as intelligence quotient and reading ability in offspring. No randomised trial data exist for iodine supplementation in mild-moderate iodine-deficient pregnant women. It is possible to combine population interventions to reduce population salt intake with salt iodisation programmes in order to maintain adequate levels of iodine nutrition.

The study has established that the UK voluntary mobile phone takeback network can be characterised as three distinctive flows: information flow; product flow (handsets and related accessories); and incentives flow. Over 100 voluntary schemes offering online takeback of mobile phone handsets were identified. The schemes are operated by manufacturers, retailers, mobile phone network service operators, charities and by mobile phone reuse, recycling and refurbishing companies. The latter two scheme categories offer the highest level of convenience and ease of use to their customers. Approximately 83% of the schemes are either for-profit/commercial-oriented and/or operate to raise funds

    1992-07-01

    A review is presented of the evolution of UK liquid hydrogen (LH2) programs into the testing of low- and higher-pressure engines for upper stage applications with attention given to the production of LH2. The engine requirements are examined of launchers such as the Black Knight and Black Prince vehicles and LOX/LH2 upper stages for the European Launcher Development Organization (ELDO). High-energy second and third stages are described for the ELDO vehicles, and injector types and thrust-chamber designs are illustrated for the use of LH2/LOX. Successful firings of the RZ-20 chamber are reported, and the production of liquid hydrogen is shown to be adequate for testing and usage over all of the experimental phases. Developments from the LH2 programs in the UK can provide technologies for current items such as the propellant feed lines for the Ariane program.

    2011-04-16

    To establish the current status of canine hydrotherapy in the UK and to ascertain information regarding the current use of hydrotherapy, a questionnaire was sent to 152 hydrotherapy centres throughout the UK, from which 89 responded. Hydrotherapy was found to be a rapidly growing business. Stand-alone centres were in existence; however, many centres were connected to other businesses, including boarding kennels and general practice veterinary surgeries. The dogs using the facility were mainly pedigree breeds, particularly labrador retrievers (30 per cent), and the most commonly encountered conditions were rupture of the cranial cruciate ligament (25 per cent), hip dysplasia (24 per cent) and osteoarthritis (18 per cent). The proportion of qualified versus unqualified staff varied between centres, highlighting a need for improved regulation of this aspect of the industry. However, all the dogs treated by the hydrotherapy centres surveyed were direct veterinary referrals, suggesting a good degree of professionalism in the field and a high regard for the benefits of hydrotherapy.

  5. Assessing the susceptibility of two UK estuaries to nutrient enrichment

    Kadiri, Margaret; Bockelmann-Evans, Bettina; Rauen, William B.

    2014-10-01

    The susceptibility of two UK estuaries, the Severn and Solva Estuaries to the risks and impacts of nutrient enrichment was investigated in this study by examining nutrients, dissolved oxygen (DO) and turbidity concentrations in the estuaries and applying a risk assessment model based on the UK's Comprehensive Studies Task Team (CSTT) modelling approach. Both estuaries were found to be nutrient enriched. However, there was no evidence of oxygen depletion in the Severn and algal blooms were not observed due to high turbidity, strong tidal currents and tidally induced vertical mixing conditions in the estuary. Although algal blooms were observed in the Solva Estuary, the estuary was well-oxygenated due to the relatively high water exchange rate and consistent rapid flushing in the estuary. The conditions in the Solva Estuary were predicted to be favourable for phytoplankton productivity and the wider potential implications for future water quality protection strategies in the Solva were discussed.

    After an AGU Congressional Science Fellowship in 1997-1998,I decided to pursue science policy further. I spied an ad in the Sunday Washington Post advertising for someone with a science degree, who also had knowledge of the United Kingdom, and science policy experience on Capitol Hill. In addition to my Ph.D. from the University of California at Los Angeles and the Congressional Science Fellowship, I had spent two years in the U.K. as a post-doc at Queen Mary and Westfield College in London.I applied for the job, which was at the British Embassy in Washington, D.C., and was hired. The UK Foreign Office has a tradition of hiring many of its embassy staff locally; they consider knowledge of local politics and issues very use ful for their interests. Now I cover hard science issues, including space and the Internet for Her Majesty's Government.

    Despite well-established treatment regimens, tuberculosis (TB) remains a public health burden; it disproportionately affects poor and marginalized populations who may not have access to social support, including migrants, homeless people and those dependent on drugs or alcohol. There is a clearly demonstrated need for housing and other appropriate social support, as part of a package of integrated clinical and social care. However, TB prevention and control efforts in the UK often do not address the specific vulnerabilities of these groups and it can be a challenge to support the continued TB treatment of these underserved populations. This challenge is exacerbated by complex issues concerning funding, immigration and the law. In this paper, we have reviewed current UK guidance and legislation, discussed several case studies and highlighted examples of existing models of community support for TB patients. Finally, we lay out our recommendations for ensuring a co-ordinated, whole system approach to successful TB treatment.

A survey of the activities of the voluntary mobile phone takeback schemes was undertaken in 2008 to: identify and evaluate the takeback schemes operating in the UK; determine the target groups from whom handsets are collected; and assess the collection, promotion and advertising methods used by the schemes. In addition, the survey sought to identify and critically evaluate the incentives offered by the takeback schemes, evaluate their ease and convenience of use; and determine the types, qualities and quantities of mobile phones they collect. The study has established that the UK voluntary mobile phone takeback network can be characterised as three distinctive flows: information flow; product flow (handsets and related accessories); and incentives flow. Over 100 voluntary schemes offering online takeback of mobile phone handsets were identified. The schemes are operated by manufacturers, retailers, mobile phone network service operators, charities and by mobile phone reuse, recycling and refurbishing companies. The latter two scheme categories offer the highest level of convenience and ease of use to their customers. Approximately 83% of the schemes are either for-profit/commercial-oriented and/or operate to raise funds

    NATO describes 'Role 4' military medical services as those provided for the definitive care of patients who cannot be treated within a theatre of operations and these are usually located in a military force's country of origin and may include the involvement of civilian medical services. The UK Defence Medical Services have a proud history of developing and providing clinical services in infectious diseases and tropical medicine, sexual health and HIV medicine, and medical microbiology and virology. These UK Role 4 Military Infection Services have adapted well to recent overseas deployments, but new challenges will arise due to current military cutbacks and a greater diversity of contingency operations in the future. Further evidence-based development of these services will require leadership by military clinicians and improved communication and support for 'reach-back' services. PMID:24109133

    Positive progress has continued in the past three years for women in physics in the UK. The Institute of Physics has aggressively advocated and organized initiatives for women in science through its Diversity Programme and its Women in Physics Group. Surveys are routinely carried out and acted upon, most recently on postdoctoral researchers and childcare issues. The Institute's Juno Award program encourages higher education institutes to address the underrepresentation of women in physics. The UK Resource Centre for Women in SET (science, engineering, and technology) provides resources and support for women working in physics and other science and engineering disciplines. The Equality Act of 2010 provides renewed focus on equality and a framework within which women physicists can continue to push for progress. The recent achievements of women physicists are noted.

  11. The moral economy of austerity: analysing UK welfare reform.

    Morris, Lydia

    2016-03-01

    This paper notes the contemporary emergence of 'morality' in both sociological argument and political rhetoric, and analyses its significance in relation to ongoing UK welfare reforms. It revisits the idea of 'moral economy' and identifies two strands in its contemporary application; that all economies depend on an internal moral schema, and that some external moral evaluation is desirable. UK welfare reform is analysed as an example of the former, with reference to three distinct orientations advanced in the work of Freeden (1996), Laclau (2014), and Lockwood (1996). In this light, the paper then considers challenges to the reform agenda, drawn from third sector and other public sources. It outlines the forms of argument present in these challenges, based respectively on rationality, legality, and morality, which together provide a basis for evaluation of the welfare reforms and for an alternative 'moral economy'.

    Cuts in temporary contracts has had big consequences for newly qualified nurses with regards to finding employment. This cut in contracts has resulted in a doubling in the rate of unemployment in this profession. In the past nurses emigrated to other countries for purposes like knowledge of the language or to extend their training and experience, however today the emigration has become the only way out for many professional nurses. The reputation of nurses in Spain is recognised internationally, with the UK being one of the countries with the largest demand for Spanish nurses. Due to the great amount of job opportunities that are emerging in the UK, nurses need help and guidance in their careers, and also nurses need training in areas such as Professional Body, developing a curriculum, facing an interview etc...

  13. Autoinflammatory gene polymorphisms and susceptibility to UK juvenile idiopathic arthritis

    2013-01-01

    Background To investigate the autoinflammatory hereditary periodic fever syndrome genes MVK and TNFRSF1A, and the NLRP1 and IL1 genes, for association with juvenile idiopathic arthritis (JIA). Methods For MVK, TNFRSF1A and NLRP1 pair-wise tagging SNPs across each gene were selected and for IL1A SNPs from a prior meta-analysis were included. 1054 UK Caucasian JIA patients were genotyped by Sequenom iPlex MassARRAY and allele and genotype frequencies compared with 5380 unrelated healthy UK Caucasian controls. Results Four SNPs were significantly associated with UK JIA: rs2071374 within intron 4 of IL1A (ptrend=0.006), rs2228576 3’ of TNFRSF1A (ptrend=0.009) and 2 SNPs, rs11836136 and rs7957619, within MVK (ptrend=0.006, ptrend=0.005 respectively). In all cases the association appeared to be driven by the systemic-onset JIA (SoJIA) subtype. Genotype data for the two MVK SNPs was available in a validation cohort of 814 JIA (oligoarticular and RF negative polyarticular) cases and 3058 controls from the US. Replication was not confirmed, however, further suggesting that this association is specific to SoJIA. Conclusions These findings extend the observations of the relevance of studying monogenic loci as candidates for complex diseases. We provide novel evidence of association of MVK and TNFRSF1A with UK JIA, specifically driven by association with SoJIA and further confirm that the IL1A SNP association with SoJIA is subtype specific. Replication is required in independent cohorts. PMID:23547563

    Cardiovascular disease (CVD) presents a significant burden to the UK. This review presents data from nationally representative datasets to provide up-to-date statistics on mortality, prevalence, treatment and costs. Data focus on CVD as a whole, coronary heart disease (International Classification of Diseases (ICD):I20–25) and cerebrovascular disease (ICD:I60–69); however, where available, other cardiovascular conditions are also presented. In 2012, CVD was the most common cause of death in the UK for women (28% of all female deaths), but not for men, where cancer is now the most common cause of death (32% of all male deaths). Mortality from CVD varies widely throughout the UK, with the highest age-standardised CVD death rates in Scotland (347/100 000) and the North of England (320/100 000 in the North West). Prevalence of coronary heart disease is also highest in the North of England (4.5% in the North East) and Scotland (4.3%). Overall, around three times as many men have had a myocardial infarction compared with women. Treatment for CVD is increasing over time, with prescriptions and operations for CVD having substantially increased over the last two decades. The National Health Service in England spent around £6.8 billion on CVD in 2012/2013, the majority of which came from spending on secondary care. Despite significant declines in mortality in the UK, CVD remains a considerable burden, both in terms of health and costs. Both primary and secondary prevention measures are necessary to reduce both the burden of CVD and inequalities in CVD mortality and prevalence. PMID:26041770

    Traditionally, the simulation of regional ocean, wave and atmosphere components of the Earth System have been considered separately, with some information on other components provided by means of boundary or forcing conditions. More recently, the potential value of a more integrated approach, as required for global climate and Earth System prediction, for regional short-term applications has begun to gain increasing research effort. In the UK, this activity is motivated by an understanding that accurate prediction and warning of the impacts of severe weather requires an integrated approach to forecasting. The substantial impacts on individuals, businesses and infrastructure of such events indicate a pressing need to understand better the value that might be delivered through more integrated environmental prediction. To address this need, the Met Office, NERC Centre for Ecology & Hydrology and NERC National Oceanography Centre have begun to develop the foundations of a coupled high resolution probabilistic forecast system for the UK at km-scale. This links together existing model components of the atmosphere, coastal ocean, land surface and hydrology. Our initial focus has been on a 2-year Prototype project to demonstrate the UK coupled prediction concept in research mode. This presentation will provide an update on UK environmental prediction activities. We will present the results from the initial implementation of an atmosphere-land-ocean coupled system, including a new eddy-permitting resolution ocean component, and discuss progress and initial results from further development to integrate wave interactions in this relatively high resolution system. We will discuss future directions and opportunities for collaboration in environmental prediction, and the challenges to realise the potential of integrated regional coupled forecasting for improving predictions and applications.

    2015-01-01

    Introduction Reducing premature death is a key priority for the UK National Health Service (NHS). NHS Ambulance services treat approximately 30 000 cases of suspected cardiac arrest each year but survival rates vary. The British Heart Foundation and Resuscitation Council (UK) have funded a structured research programme—the Out of Hospital Cardiac Arrest Outcomes (OHCAO) programme. The aim of the project is to establish the epidemiology and outcome of OHCA, explore sources of variation in outcome and establish the feasibility of setting up a national OHCA registry. Methods and analysis This is a prospective observational study set in UK NHS Ambulance Services. The target population will be adults and children sustaining an OHCA who are attended by an NHS ambulance emergency response and where resuscitation is attempted. The data collected will be characterised broadly as system characteristics, emergency medical services (EMS) dispatch characteristics, patient characteristics and EMS process variables. The main outcome variables of interest will be return of spontaneous circulation and medium—long-term survival (30 days to 10-year survival). Ethics and dissemination Ethics committee permissions were gained and the study also has received approval from the Confidentiality Advisory Group Ethics and Confidentiality committee which provides authorisation to lawfully hold identifiable data on patients without their consent. To identify the key characteristics contributing to better outcomes in some ambulance services, reliable and reproducible systems need to be established for collecting data on OHCA in the UK. Reports generated from the registry will focus on data completeness, timeliness and quality. Subsequent reports will summarise demographic, patient, process and outcome variables with aim of improving patient care through focus quality improvement initiatives. PMID:26428332

    AstroGrid is the UK's Virtual Observatory (VO) initiative. It brings together the principal astronomical data centres in the UK, and has been funded to the tune of ˜pounds 5M over the next three years, via PPARC, as part of the UK e--science programme. Its twin goals are the provision of the infrastructure and tools for the federation and exploitation of large astronomical (X-ray to radio), solar and space plasma physics datasets, and the delivery of federations of current datasets for its user communities to exploit using those tools. Whilst AstroGrid's work will be centred on existing and future (e.g. VISTA) UK datasets, it will seek solutions to generic VO problems and will contribute to the developing international virtual observatory framework: AstroGrid is a member of the EU-funded Astrophysical Virtual Observatory project, has close links to a second EU Grid initiative, the European Grid of Solar Observations (EGSO), and will seek an active role in the development of the common standards on which the international virtual observatory will rely. In this paper we shall primarily describe the concrete plans for AstroGrid's one-year Phase A study, which will centre on: (i) the definition of detailed science requirements through community consultation; (ii) the undertaking of a ``functionality market survey" to test the utility of existing technologies for the VO; and (iii) a pilot programme of database federations, each addressing different aspects of the general database federation problem.

  18. Can UK fossil fuel emissions be determined by radiocarbon measurements?

    2016-04-01

    The GAUGE project evaluates different methods to estimate UK emissions. However, estimating carbon dioxide emissions as a result of fossil fuel burning is challenging as natural fluxes in and out of the atmosphere are very large. Radiocarbon (14C) measurements offer a way to specifically measure the amount of recently added carbon dioxide from fossil fuel burning. This is possible as, due to their age, all the radiocarbon in fossil fuels has decayed. Hence the amount of recently added CO2 from fossil fuel burning can be measured as a depletion of the 14C content in air. While this method has been successfully applied by several groups on a city or a regional scale, this is the first attempt at using the technique for a national emission estimate. Geographically the UK, being an island, is a good location for such an experiment. But are 14CO2 measurements the ideal solution for estimating fossil fuel emissions as they are heralded to be? Previous studies have shown that 14CO2emissions from the nuclear industry mask the 14C depletion caused by fossil fuel burning and result in an underestimation of the fossil fuel CO2. While this might not be a problem in certain regions around the world, many countries like the UK have a substantial nuclear industry. A correction for this enhancement from the nuclear industry can be applied but are invariably difficult as 14CO2emissions from nuclear power plants have a high temporal variability. We will explain how our sampling strategy was chosen to minimize the influence form the nuclear industry and why this proved to be challenging. In addition we present the results from our ground based measurements to show why trying to estimate national emissions using radiocarbon measurements was overambitious, and how practical the technique is for the UK in general.

    A focused repeat national audit of sexual history-taking was conducted in genitourinary (GU) medicine clinics in the UK in 2010, addressing several areas of practice under-performance identified in the baseline 2008 national audit. The case-notes of 4285 patients were audited. An increase in documentation was observed for all measures, except legibility which was unchanged. Despite the overall improvement, several measures (chaperone offer, condom usage and four of five aspects of HIV risk assessment) remained below target.

    Following the development of 1st Generation systems in the 1970s, thermal imaging has been in service with the UK armed forces for over 25 years and has proven itself to be a battle winning technology. More recently the wider accessibility to similar technologies within opposing forces has reduced the military advantage provided by these 1st Generation systems and a clear requirement has been identified by the UK MOD for thermal imaging sensors providing increased detection, recognition and identification (DRI) ranges together with a simplified logistical deployment burden and reduced through-life costs. In late 2005, the UK MOD initiated a programme known as "Albion" to develop high performance 3rd Generation single waveband infrared detectors to meet this requirement. At the same time, under a separate programme supporting higher risk technology, a dual waveband infrared detector was also developed. The development phase of the Albion programme has now been completed and prototype detectors are now available and have been integrated into demonstration thermal imaging cameras. The Albion programme has now progressed into the second phase, incorporating both single and dual waveband devices, focussing on low rate initial production (LRIP) and qualification of the devices for military applications. All of the detectors have been fabricated using cadmium mercury telluride material (CMT), grown by metal organic vapour phase epitaxy (MOVPE) on low cost, gallium arsenide (GaAs) substrates and bump bonded to the silicon read out circuit (ROIC). This paper discusses the design features of the 3rd Generation detectors developed in the UK together with the results obtained from the prototype devices both in the laboratory and when integrated into field deployable thermal imaging cameras.

    As part of the process of adopting the WHO standard in the United Kingdom, the Royal College of Paediatrics and Child Health (RCPCH) was commissioned by the UK Department of Health to design new UK-WHO growth charts. The working group for this project combined expertise ranging from statistics and graphic design to qualitative research, as well as paediatrics, nursing and dietetics. New charts for children under 4 years were published in 2009 and are now widely used in the UK and beyond (www.growthcharts.rcpch.ac.uk). This paper will describe what we have learned in general about the process of designing charts and how these principles were applied to the design of a novel chart designed specifically for sick and premature infants. A successful design first requires clarity about the exact purpose of the chart and who will use it. The layout of the chart can then be varied in many ways to fit that use and ensure users are not misled. Users need consistent and well-evidenced rules for chart use. Drafting the instructions serves as a powerful test of the validity and clarity of the design. However, charts need also to be formally evaluated, as expert views will not reflect those of the average user. The Neonatal and Infant Close Monitoring (NICM) chart included various novel design features, including date boxes for gestational age adjustment and low SD lines to help assess very small infants. It was evaluated at three stages using plotting exercises and each phase led to substantial design changes. Growth charts are conceptually very complex, with the capacity to mislead as well as inform and should always be formally evaluated before implementation.

    This study aimed to assess the whole grain (WG) content of foods consumed in the UK which include ingredients that retain all three structural components of the grain, and contained ⩾10% WG. Dietary data from seven studies with 10,474 UK subjects were examined for foods containing WG. The WG content was then determined from ingredient lists, manufacturers' information and recipes. 372 food descriptors from nine food groups (4.4% of all food codes) contained ⩾10% WG. Of these 372 foods, 31.5% contained ⩾51%, 30.6% 25-50%, and 37.9% 10-24% WG dry matter as eaten. The relatively small number of WG foods identified in the total number of foods consumed confirms the low contribution of WG foods to the overall pattern of foods consumed in the UK. Since foods containing <51% WG accounted for the majority of WG food codes identified, recognising the importance of these foods to WG intake is essential. PMID:27507498

    2009-09-01

    The Met Office and the Environment Agency in the UK have set up a joint Flood Forecasting Centre (FFC), based at the London offices of the Met Office. This partnership will improve the UK's ability to respond to flooding events by providing an earlier national forecasting and alert service to central and local government departments so as to give them more time to prepare for floods and reduce the risk of loss of life and damage to property. The creation of the centre is in response to a key recommendation of Sir Michael Pitt's Review following the summer 2007 floods over the UK. For the first time, the FFC combines the Environment Agency's expertise in flood risk management and the Met Office's expertise in weather forecasting under one roof. My presentation will describe the benefits it will bring to the emergency responder community. It will also cover the tools available to the centre such as the new generation of high resolution weather models now coming on line. As a result, flood forecasting and warning systems, (which historically have been based on the lack of sufficiently fine scale rainfall information), need to be revisited in the light of the new meteorological modelling capabilities. This is particularly true for surface water flooding, where these new capabilities offer, for the first time, the possibility of providing credible alerts.

    2010-01-01

    Over the past decade, questions regarding how to reduce human contributions to climate change have become more commonplace and non-nation state actors—such as businesses, non-government organizations, celebrities—have increasingly become involved in climate change mitigation and adaptation initiatives. For these dynamic and rapidly expanding spaces, this letter provides an accounting of the methods and findings from a 2007 assessment of greenhouse gas (GHG) emissions in the UK music industry. The study estimates that overall GHG emissions associated with the UK music market are approximately 540 000 t CO2e per annum. Music recording and publishing accounted for 26% of these emissions (138 000 t CO2e per annum), while three-quarters (74%) derived from activities associated with live music performances (400 000 t CO2e per annum). These results have prompted a group of music industry business leaders to design campaigns to reduce the GHG emissions of their supply chains. The study has also provided a basis for ongoing in-depth research on CD packaging, audience travel, and artist touring as well as the development of a voluntary accreditation scheme for reducing GHG emissions from activities of the UK music industry.

    Aim To evaluate current clinical practice in the UK in the management of the anophthalmic socket; choice of enucleation, evisceration, type of orbital implant, wrap, motility pegging and complications. Methods All consultant ophthalmologists in the UK were surveyed by postal questionnaire. Questions included their practice subspecialty and number of enucleations and eviscerations performed in 2003. Specific questions addressed choice of implant, wrap, motility pegging and complications. Results 456/896 (51%) consultants responded, of which 162 (35%) had a specific interest in oculoplastics, lacrimal, orbits or oncology. Only 243/456 (53%) did enucleations or eviscerations. 92% inserted an orbital implant after primary enucleation, 69% after non‐endophthalmitis evisceration, whereas only 43% did so after evisceration for endophthalmitis (50% as a delayed procedure). 55% used porous orbital implants (porous polyethylene, hydroxyapatite or alumina) as their first choice and 42% used acrylic. Most implants inserted were spherical, sized 18–20 mm in diameter. 57% wrapped the implant after enucleation, using salvaged autogenous sclera (20%), donor sclera (28%) and synthetic Vicryl or Mersilene mesh (42%). A minority (7%) placed motility pegs in selected cases, usually as a secondary procedure. 14% of respondents reported implant exposure for each type of procedure and extrusion was reported by 4% after enucleation and 3% after evisceration. Conclusions This survey highlights contemporary anophthalmic socket practice in the UK. Most surgeons use porous orbital implants with a synthetic wrap after enucleation and only few perform motility pegging. PMID:17151061

  7. Developing a Broadband Adoption Model in the UK Context

    Dwivedi, Yogesh K.; Mustafee, Navonil; Williams, Michael D.; Lal, Banita

    This research examines the factors affecting the consumer adoption of broadband in the United Kingdom. A conceptual model of broadband adoption was developed by selecting and justifying a number of relevant constructs from the technology adoption literature. The model was then empirically tested by employing survey data that was randomly collected from 358 UK broadband consumers. The findings suggest that, with the exception of one construct that was included in the conceptual model (namely, knowledge), all of the con structs significantly influence consumers when adopting broadband in a UK household. The significant constructs include relative advantage, utilitarian outcomes, hedonic outcomes, primary influence, facilitating conditions resources, and self-efficacy. Furthermore, when considering the behavioral intention and facilitating conditions resources constructs together, they significantly explain UK broad band adoption behavior. The theoretical contri bution of this research is that it determines and integrates the appropriate constructs from the technology adoption literature in order to enhance the knowledge of technology adoption from the consumer's perspective. This research has implications for policy makers and broadband providers since the results of this study can be exploited by the aforementioned stakeholders in order to encourage and promote the adoption and usage of broadband among the general population.

  8. US line-ups outperform UK line-ups

    2016-01-01

    In the USA and the UK, many thousands of police suspects are identified by eyewitnesses every year. Unfortunately, many of those suspects are innocent, which becomes evident when they are exonerated by DNA testing, often after having been imprisoned for years. It is, therefore, imperative to use identification procedures that best enable eyewitnesses to discriminate innocent from guilty suspects. Although police investigators in both countries often administer line-up procedures, the details of how line-ups are presented are quite different and an important direct comparison has yet to be conducted. We investigated whether these two line-up procedures differ in terms of (i) discriminability (using receiver operating characteristic analysis) and (ii) reliability (using confidence–accuracy characteristic analysis). A total of 2249 participants watched a video of a crime and were later tested using either a six-person simultaneous photo line-up procedure (USA) or a nine-person sequential video line-up procedure (UK). US line-up procedure yielded significantly higher discriminability and significantly higher reliability. The results do not pinpoint the reason for the observed difference between the two procedures, but they do suggest that there is much room for improvement with the UK line-up. PMID:27703695

    The majority of the UK population is either overweight or obese. Health economists, nutritionists and doctors are calling for the UK to follow the example of other European countries and introduce a tax on soft drinks as a result of the perception that high intakes contribute to diet-related disease. We use a demand model estimated with household-level data on beverage purchases in the UK to investigate the effects of a tax on soft drink consumption. The model is a Quadratic Almost Ideal Demand System, and censoring is handled by applying a double hurdle. Separate models are estimated for low, moderate and high consumers to allow for a differential impact on consumption between these groups. Applying different hypothetical tax rates, we conclude that understanding the nature of substitute/complement relationships is crucial in designing an effective policy as these relationships differ between consumers depending on their consumption level. The overall impact of a soft drink tax on calorie consumption is likely to be small. PMID:24677314

    Following the death of a British National on foreign soil, a primary investigation is conducted by the authorities of that country; HM Coroner and the United Kingdom police have no jurisdiction to conduct investigations abroad. Upon repatriation of a body, the legal investigation in the UK remains largely unchanged since the publication of the "harmonisation of medico-legal autopsy rules" (1999) and the passing of the Coroners and Justice Act (2009). We identified 44 cases within a 10-year period. An invasive autopsy had been performed abroad in 25 cases; an autopsy report was received prior to UK autopsy in one case. Seven cases showed incomplete evisceration; the absence of part or whole organs was recorded in 11 cases. Toxicology was performed abroad in five cases. Recurring technical difficulties related chiefly to embalming, including difficulty with dissection and noxious fumes. When an autopsy had been performed abroad, the time to UK inquest was prolonged by an average of seven months. A verdict of unlawful killing was returned in nine cases. The discussion expands on these issues, and attempts to offer reasoned explanation where possible. Two cases are used as exemplars to highlight difficulties to both the pathologist and Coroner. This casework remains rare but the potential problems include: absence of tissue; lack of information; technical difficulties; and a disproportionately high number of unlawful killings, making clear the need for experience and caution when making the post mortem examination.

    It has long been understood that accurate prediction and warning of the impacts of severe weather requires an integrated approach to forecasting. For example, high impact weather is typically manifested through various interactions and feedbacks between different components of the Earth System. Damaging high winds can lead to significant damage from the large waves and storm surge along coastlines. The impact of intense rainfall can be translated through saturated soils and land surface processes, high river flows and flooding inland. The substantial impacts on individuals, businesses and infrastructure of such events indicate a pressing need to understand better the value that might be delivered through more integrated environmental prediction. To address this need, the Met Office, NERC Centre for Ecology & Hydrology and NERC National Oceanography Centre have begun to develop the foundations of a coupled high resolution probabilistic forecast system for the UK at km-scale. This links together existing model components of the atmosphere, coastal ocean, land surface and hydrology. Our initial focus has been on a 2-year Prototype project to demonstrate the UK coupled prediction concept in research mode. This presentation will provide an update on UK environmental prediction activities. We will present the results from the initial implementation of an atmosphere-land-ocean coupled system and discuss progress and initial results from further development to integrate wave interactions. We will discuss future directions and opportunities for collaboration in environmental prediction, and the challenges to realise the potential of integrated regional coupled forecasting for improving predictions and applications.

    Purpose The purpose of this paper is to explore selective leadership approaches in the context of dentistry in the UK. Design/methodology/approach This is a conceptual paper utilising published sources from relevant literature about leadership theory and practice and the policy background to dentistry in the UK. Findings This paper suggests that there is merit in identifying and applying an eclectic mix of leadership theory to the case of dentistry. It offers insight into individual aspects of the leadership role for dentists and applies this to the dental context. It also contrasts these individual approaches with shared leadership and suggests this may also be relevant to dentistry. It highlights the fact that leadership will be of growing concern for dentistry in the light of recent policy changes. Research limitations/implications This paper points out that there are developmental implications depending on the particular approach taken. It argues that leadership development will become increasingly important in dentistry in the UK. Originality/value This paper addresses a topic that has so far received limited attention in the literature.

    Seasonal river flow forecasts are beneficial for planning agricultural activities, river navigation, and for management of reservoirs for public water supply and hydropower generation. In the United Kingdom (UK), skilful seasonal river flow predictions have previously been limited to catchments in lowland (southern and eastern) regions. Here we show that skilful long-range forecasts of winter flows can now be achieved across the whole of the UK. This is due to a remarkable geographical complementarity between the regional geological and meteorological sources of predictability for river flows. Forecast skill derives from the hydrogeological memory of antecedent conditions in southern and eastern parts of the UK and from meteorological predictability in northern and western areas. Specifically, it is the predictions of the atmospheric circulation over the North Atlantic that provides the skill at the seasonal timescale. In addition, significant levels of skill in predicting the frequency of winter high flow events is demonstrated, which has the potential to allow flood adaptation measures to be put in place.

  14. How fair is access to more prestigious UK universities?

    Now that most UK universities have increased their tuition fees to £9,000 a year and are implementing new Access Agreements as required by the Office for Fair Access, it has never been more important to examine the extent of fair access to UK higher education and to more prestigious UK universities in particular. This paper uses Universities and Colleges Admissions Service (UCAS) data for the period 1996 to 2006 to explore the extent of fair access to prestigious Russell Group universities, where 'fair' is taken to mean equal rates of making applications to and receiving offers of admission from these universities on the part of those who are equally qualified to enter them. The empirical findings show that access to Russell Group universities is far from fair in this sense and that little changed following the introduction of tuition fees in 1998 and their initial increase to £3,000 a year in 2006. Throughout this period, UCAS applicants from lower class backgrounds and from state schools remained much less likely to apply to Russell Group universities than their comparably qualified counterparts from higher class backgrounds and private schools, while Russell Group applicants from state schools and from Black and Asian ethnic backgrounds remained much less likely to receive offers of admission from Russell Group universities in comparison with their equivalently qualified peers from private schools and the White ethnic group.

    This report describes a scoping study conducted in order to establish whether pharmaceutical compounds may be present in UK estuaries. Surface water samples collected from five UK estuaries were analysed for the presence of 14 pharmaceutical compounds selected from the priority lists of the UK Environment Agency and the Oslo and Paris Commission (OSPAR). The pharmaceutical compounds/metabolites clofibric acid, clotrimazole, dextropropoxyphene, diclofenac, ibuprofen, mefenamic acid, propranolol, tamoxifen and trimethoprim were detected at measurable concentrations in the samples collected. The concentrations of erythromycin, lofepramine, paracetamol, sulfamethoxazole and acetyl-sulfamethoxazole were all below the limits of detection of the methods used (between 4 and 20 ng l(-1)). The anti-fungal agent clotrimazole was the most frequently detected at a maximal concentration of 22 ng l(-1) and a median concentration of 7 ng l(-1). The analgesic compound ibuprofen was detected at a maximal concentration of approximately 930 ng l(-1) and a median concentration of 48 ng l(-1), whilst the other pharmaceutical compounds were detected between the limits of detection of the method used and 570 ng l(-1).

    Self-poisoning by ingestion or inhalation is common, and it is important to study its various epidemiological manifestations with clear definitions. Data on fatal self-poisonings are recorded nationally within the UK and are codified according to the International Classification of Diseases (ICD) revision relevant at the time. Most fatal self-poisonings are codified as suicides, accidental deaths or undetermined deaths (‘open verdicts’). Non-fatal self-poisoning data, whether accidental or as a manifestation of deliberate self-harm, are recorded through hospital discharge information nationally but are not routinely published in the same way as mortality data. The bulk of the UK's published epidemiological information on nonfatal self-poisoning episodes is largely based on individual hospitals' admission or discharge records (‘special studies’). After establishing definitions for different self-poisoning categories we discuss the published data on self-poisoning as they relate to suicide, accidental self-poisoning and deliberate self-harm in the UK.

    Background Exposure to alcohol consumption and product imagery in films is associated with increased alcohol consumption among young people, but the extent to which exposure also occurs through television is not clear. We have measured the occurrence of alcohol imagery in prime-time broadcasting on UK free-to-air television channels. Methods Occurrence of alcohol imagery (actual use, implied use, brand appearances or other reference to alcohol) was measured in all broadcasting on the five most popular UK television stations between 6 and 10 p.m. during 3 weeks in 2010, by 1-min interval coding. Results Alcohol imagery occurred in over 40% of broadcasts, most commonly soap operas, feature films, sport and comedies, and was equally frequent before and after the 9 p.m. watershed. Brand appearances occurred in 21% of programmes, and over half of all sports programmes, a third of soap operas and comedies and a fifth of advertising/trailers. Three brands, Heineken, Budweiser and Carlsberg together accounted for ∼40% of all brand depictions. Conclusions Young people are exposed to frequent alcohol imagery, including branding, in UK prime-time television. It is likely that this exposure has an important effect on alcohol consumption in young people. PMID:23929886

    Shell U.K. Exploration and Production (Shell), acting as operator for a consortium of companies, has described plans for the two-phase development of Galleon gas field, located 50 miles from the Shell/Esso gas processing plant at Bacton, Norfolk, in 82 ft of water. The field has estimated reserves of 1.4 Tcf. Phase 1 development will cost [Brit pounds]300 million ($500 million); and first production is expected in late 1994. British Gas has agreed to purchase at least Phase 1 gas. Shell will be the operator for the development. A preliminary costsharing arrangement has been agreed to by the co-venturers to bridge the period until equities are determined. The consortium comprises Shell and Esso, with 40% each, and Conoco (U.K.) Ltd. and Oryx U.K. Energy Co., each with 10%. The field is located in Shell/Esso Blocks 48/14, 19a and 20a, and Conoco/Oryx Block 48/15a. Galleon will be the sixth gas field to be developed in the Southern North Sea by Shell, the operator for Shell and Esso. It will be the third field in the Sole Pit area, where total reserves found by Shell/Esso are about 3.0 Tcf.

    Cosmogenic beryllium-7 has been widely employed as a sediment tracing tool and continued development of its use as a soil erosion tracer requires knowledge of fallout temporal dynamics. Data regarding beryllium-7 fallout in the UK are scarce and here the authors provide a record of beryllium-7 fallout in southwest England spanning a two-year period. A monthly fallout record was developed for Plymouth, UK using regular rainfall sampling to determine beryllium-7 rainfall activity concentration (Bq L(-1)) and deposition flux (Bq m(-2)). Data showed a general tendency for higher activity during the spring/summer months and lower activity in the autumn/winter months. Comparison with data for other UK sites (Chilton and Aberporth) for the same period found significant differences in (7)Be activity in rainwater and lower variability in Plymouth than Chilton and Aberporth. Total deposition was largely controlled by rainfall in Plymouth although regression coefficients suggested greater importance of other atmospheric controls at the Chilton and Aberporth sites. Use of a deposition proportion to rainfall proportion ratio identified periods when deposition was influenced by varying (7)Be activity in rainfall. Broad ranges in ratios were found for Chilton and Aberporth and this has implications for sediment tracer studies requiring estimates of (7)Be deposition flux across months or seasons. PMID:27155526

    The patterns of seasonal variation of radon concentrations were measured in 91 homes in five regions of the UK over a period of two years. The results showed that there was no significant difference between the regions in the pattern or magnitude of seasonal variation in radon concentrations. The arithmetic mean variation was found to be close to that found previously in the UK national survey. Differences in the pattern between the two years of the study were not significant. Two-thirds of homes in the study followed the expected pattern of high radon in the winter and low radon in the summer. Most of the rest showed little seasonal variation, and a few showed a reversed seasonal pattern. The study does not provide any clear evidence for the recorded house characteristics having an effect on the seasonal variation in radon concentrations in UK homes, though the statistical power for determining such effects is limited in this study. The magnitude of the seasonal variation varied widely between homes. Analysis of the individual results from the homes showed that because of the wide variation in the amount of seasonal variation, applying seasonal correction factors to the results of three-month measurements can yield only relatively small improvements in the accuracy of estimates of annual mean concentrations.

  1. Maintaining quality in the UK breast screening program

    NASA Astrophysics Data System (ADS)

    Gale, Alastair

    2010-02-01

    Breast screening in the UK has been implemented for over 20 years and annually nearly two million women are now screened with an estimated 1,400 lives saved. Nationally, some 700 individuals interpret screening mammograms in almost 110 screening centres. Currently, women aged 50 to 70 are invited for screening every three years and by 2012 this age range will increase to 47 - 73 years. There is a rapid ongoing transition from using film mammograms to full field digital mammography such that in 2010 every screening centre will be partly digital. An early, and long running, concern has been how to ensure the highest quality of imaging interpretation across the UK, an issue enhanced by the use of a three year screening interval. To partly address this question a self assessment scheme was developed in 1988 and subsequently implemented nationally in the UK as a virtually mandatory activity. The scheme is detailed from its beginnings, through its various developments to current incarnation and future plans. This encompasses both radiological (single view screening, two view screening, mammographic film and full field digital mammography) as well as design changes (cases reported by means of: form filling; PDA; tablet PC; iPhone, and the internet). The scheme provides a rich data source which is regularly studied to examine different aspects of radiological performance. Overall it aids screening radiologists by giving them regular access to a range of difficult exemplar cases together with feedback on their performance as compared to their peers.

  3. The EC novel foods Regulation--a UK perspective.

    PubMed

    Tomlinson, N

    1998-01-01

    On 15 May 1997 the EC novel foods Regulation came into effect introducing a statutory pre-market approval system for novel foods across the whole of the European Union. A novel food is defined as a food which has not been consumed to a significant degree and includes foods containing or obtained from genetically modified organisms. The Regulation envisages an initial safety assessment at Member State level, although centralized procedures are available to resolve any objections between Member States. The most controversial aspect of the Regulation relates to the provisions for labelling genetically modified foods. Within the framework of the Regulation there is scope for labelling to be considered on a case by case basis, although the UK is pressing for all foods which may contain genetically modified material to be clearly labelled. To ensure that all Member States follow a consistent approach to the safety assessment of novel foods, the Commission has published a series of guidelines to accompany the regulation. The UK already has a well-developed system for assessing the safety of novel foods dating back to the approval of the first novel food in the UK in 1983.

  4. Potential environmental impacts of offshore UK geological CO2 storage

    Geological carbon dioxide storage in the United Kingdom (UK) will almost certainly be entirely offshore, with storage for over 100 years' worth of UK CO2 output from industry and power generation in offshore depleted hydrocarbon fields and sandstone formations. Storage capacity can be limited by the increase in formation water pressure upon CO2 injection, therefore removal and disposal of formation waters ('produced waters') can control formation water pressures, and increase CO2 storage capacity. Formation waters could also be produced during CO2-Enhanced Oil Recovery (CO2-EOR). The precedent from current UK North Sea hydrocarbon extraction is to 'overboard' produced waters into the ocean, under current regulations. However, laboratory and field scale studies, with an emphasis on the effects on onshore shallow potable groundwaters, have shown that CO2 dissolution in formation waters during injection and storage acidifies the waters and promotes mobilisation from the reservoir sandstones of major and trace elements into solution, including heavy metals. Eight of these elements are specifically identified in the UK as potentially hazardous to the marine environment (As, Cd, Cr, Cu, Hg, Ni, Pb, Zn). A comparison was made between the concentrations of these eight trace elements in the results of laboratory batch leaching experiments of reservoir rock in CO2-rich saline solutions and overboarded waters from current offshore UK hydrocarbon production. This showed that, taking the North Sea as a whole, the experimental results fall within the range of concentrations of current oil and gas activities. However, on a field-by-field basis, concentrations may be enhanced with CO2 storage, such that they are higher than waters normally produced from a particular field. Lead, nickel and zinc showed the greatest concentration increases in the experiments with the addition of CO2, with the other five elements of interest not showing any strong trends with respect to enhanced CO2

    Groundwater is a vital source of freshwater in the UK. It provides almost 30% of public water supply on average, but locally, for example in south-east England, it is constitutes nearly 90% of public supply. In addition to public supply, groundwater has a number of other uses including agriculture, industry, and food and drink production. It is also vital for maintaining river flows especially during dry periods and so is essential for maintaining ecosystem health. Recently, there have been concerns expressed about the potential impacts of shale gas development on groundwater. The UK has abundant shales and clays which are currently the focus of considerable interest and there is active research into their characterisation, resource evaluation and exploitation risks. The British Geological Survey (BGS) is undertaking research to provide information to address some of the environmental concerns related to the potential impacts of shale gas development on groundwater resources and quality. The aim of much of this initial work is to establish environmental baselines, such as a baseline survey of methane occurrence in groundwater (National methane baseline study) and the spatial relationships between potential sources and groundwater receptors (iHydrogeology project), prior to any shale gas exploration and development. The poster describes these two baseline studies and presents preliminary findings. BGS are currently undertaking a national survey of baseline methane concentrations in groundwater across the UK. This work will enable any potential future changes in methane in groundwater associated with shale gas development to be assessed. Measurements of methane in potable water from the Cretaceous, Jurassic and Triassic carbonate and sandstone aquifers are variable and reveal methane concentrations of up to 500 micrograms per litre, but the mean value is relatively low at < 10 micrograms per litre. These values compare with much higher levels of methane in aquicludes

    Both countries face considerable challenges to their rehabilitation services. Although contextually different, the problems and challenges are common to both. Two contrasting views of disability have been presented. In the UK disability may be viewed as a disaster, while in Asia illness and disability may be viewed as inevitable. Personal independence is not a universal goal of rehabilitation, because in some cultures dependence on others is an expected consequence of disability. Disability in Indonesia translates into a large burden of care for the family, whereas English families may expect greater help from the government in caring for their relative. Western rehabilitation is increasingly patient directed, whereas the Indonesian model is more likely to be determined solely by professionals. The problems observed by the team in Indonesia were remarkably similar to those experienced in the UK. A patient centered goal setting approach can be considered vital to neurological rehabilitation, although the focus of the goals set is likely to be very different in these two cultures. The fundamental importance of a multidisciplinary team is recognized in both cultures, although team working may not be easy in either situation. Managerial commitment is essential for the survival of a team, yet both structures sometimes fail to provide the necessary support. Hierarchical leadership can inhibit team development both in the UK and in Indonesia, as can frequent rotation of staff. Prescription of therapy by doctors inhibits the development of therapists in both cultures, and therefore the overall effectiveness of the team. In both the UK and Indonesia, the value of rehabilitation as a specialty is not widely recognized. The absence of life and death situations means that services are often out of the public eye, and poorly understood. However, the prevalence of disability will increase the need for rehabilitation services worldwide. Many challenges remain in both the UK and

  7. The future of flood insurance in the UK

    NASA Astrophysics Data System (ADS)

    2013-04-01

    Approximately one in seven properties in the UK (3.6 million homes and businesses) are at risk of flooding. The Adaptation Sub-Committee of the UK Committee on Climate Change reported in 2012 that development on the floodplain grew at a faster rate than elsewhere in England over the past ten years, with one in five properties in the floodplain in areas of significant risk. They concluded that current levels of investment will not keep pace with the increasing risk, noting that without additional action, climate change could almost double the number of properties at significant risk by 2035. Flood insurance can contribute to risk reduction by using pricing or restrictions on availability of cover to discourage new development in flood risk areas, or to encourage the uptake of flood resilience measures. The UK insurance market currently offers flood cover as a standard feature of domestic and small business policies, with central government providing physical protection backed up by financial protection provided by the insurance industry. This approach is unusual in not passing all or part of the flood risk to government schemes. At present, flood insurance in the UK is conducted under a series of informal agreements established between the insurance industry and the Government known as the Statement of Principles. Members of the Association of British Insurers (ABI) currently agree to cover homes at risk of flooding in return for government commitment to manage flood risk. However, this arrangement is now under threat, as the insurance industry is increasingly reluctant to bear the financial burden of flooding alone. The current Statement of Principles ends on 30 June 2013 and will not be renewed. High-risk properties may be unable to obtain insurance after the Statement of Principles expires. Unusually, insurers are arguing against a free market solution, arguing that no country in the world provides universal flood cover without some form of government-led support

    Introduction This protocol covers the first part of a two-part project funded by the Health Libraries Group and the University Health and Medical Librarians Group. It details the proposed methodology for a systematic map of the literature relating to UK bibliographic databases in the fields of health and social care. The aim of this mapping exercise is to consider ways in which UK bibliographic databases are described, considered and discussed in the published and unpublished literature. In doing so, we hope to gain a clearer sense of the ways in which UK bibliographic databases are used and viewed by the research community. It also enables the identification of any gaps in the literature for further research and discussion. This topic is important because UK databases are generally underused by researchers in the UK context and some databases are at risk of closure. A lack of access to UK databases means that researchers may miss relevant UK evidence when identifying an evidence base. Method Systematic Map. Analysis The authors will present a narrative description of the literature relating to UK bibliographic databases in the fields of health and social care. They will use tables to present descriptive information about the literature (eg, frequency tables) and use cross-tabulations to demonstrate intersecting themes. Separately, guidance on how to use the resources (eg, areas of unique content, updating frequencies, unique truncation symbols) will be sought from stakeholders and reported alongside the report narrative as a guide to usage.

    Many countries are rolling out smart electricity meters. These measure a home's total power demand. However, research into consumer behaviour suggests that consumers are best able to improve their energy efficiency when provided with itemised, appliance-by-appliance consumption information. Energy disaggregation is a computational technique for estimating appliance-by-appliance energy consumption from a whole-house meter signal. To conduct research on disaggregation algorithms, researchers require data describing not just the aggregate demand per building but also the 'ground truth' demand of individual appliances. In this context, we present UK-DALE: an open-access dataset from the UK recording Domestic Appliance-Level Electricity at a sample rate of 16 kHz for the whole-house and at 1/6 Hz for individual appliances. This is the first open access UK dataset at this temporal resolution. We recorded from five houses, one of which was recorded for 655 days, the longest duration we are aware of for any energy dataset at this sample rate. We also describe the low-cost, open-source, wireless system we built for collecting our dataset.

    The UK Functional Assessment Measure (UKFIM+FAM) is the principal outcome measure for the UK Rehabilitation Outcomes Collaborative (UKROC) national database for specialist rehabilitation. Previously validated in a mixed neurorehabilitation cohort, this study is the first to explore its psychometric properties in a stroke population, and compare left and right hemispheric strokes (LHS vs RHS). We analysed in-patient episode data from 62 specialist rehabilitation units collated through the UKROC database 2010-2013. Complete data were analysed for 1,539 stroke patients (LHS: 588, RHS: 566 with clear localisation). For factor analysis, admission and discharge data were pooled and randomised into two equivalent samples; the first for exploratory factor analysis (EFA) using principal components analysis, and the second for confirmatory factor analysis (CFA). Responsiveness for each subject (change from admission to discharge) was examined using paired t-tests and differences between LHS and RHS for the entire group were examined using non-paired t-tests. EFA showed a strong general factor accounting for >48% of the total variance. A three-factor solution comprising motor, communication and psychosocial subscales, accounting for >69% total variance, provided acceptable fit statistics on CFA (Root Mean Square Error of Approximation was 0.08 and Comparative Fit Index/ Tucker Lewis Index 0.922/0.907). All three subscales showed significant improvement between admission and discharge (p<0.001) with moderate effect sizes (>0.5). Total scores between LHS and RHS were not significantly different. However, LHS showed significantly higher motor scores (Mean 5.7, 95%CI 2.7, 8.6 p<0.001), while LHS had significantly lower cognitive scores, primarily in the communication domain (-6.8 95%CI -7.7, -5.8 p<0.001). To conclude, the UK FIM+FAM has a three-factor structure in stroke, similar to the general neurorehabilitation population. It is responsive to change during in

    In 2011, the Clinical and Translational Radiotherapy Research Working Group (CTRad) of the National Cancer Research Institute brought together UK radiotherapy physics leaders for a think tank meeting. Following a format that CTRad had previously and successfully used with clinical oncologists, 23 departments were asked to complete a pre-meeting evaluation of their radiotherapy physics research infrastructure and the strengths, weaknesses, opportunities and threats within their own centre. These departments were brought together with the CTRad Executive Group and research funders to discuss the current state of radiotherapy physics research, perceived barriers and possible solutions. In this Commentary, we summarise the submitted materials, presentations and discussions from the meeting and propose an action plan. It is clear that there are challenges in both funding and staffing of radiotherapy physics research. Programme and project funding streams sometimes struggle to cater for physics-led work, and increased representation on research funding bodies would be valuable. Career paths for academic radiotherapy physicists need to be examined and an academic training route identified within Modernising Scientific Careers; the introduction of formal job plans may allow greater protection of research time, and should be considered. Improved access to research facilities, including research linear accelerators, would enhance research activity and pass on developments to patients more quickly; research infrastructure could be benchmarked against centres in the UK and abroad. UK National Health Service departments wishing to undertake radiotherapy research, with its attendant added value for patients, need to develop a strategy with their partner higher education institution, and collaboration between departments may provide enhanced opportunities for funded research.

    2004-01-01

    INTRODUCTION: Untreated symptomatic patients with Paget-Schroetter syndrome (PSS) can sustain chronic disability from venous obstruction, with arm swelling, pain and early exercise fatigue. This may result in significant loss of occupational productivity and quality of life. For this reason, active management is recommended in the majority of the recent literature. The objective of the this study was to assess current trends of management of PSS in the UK. METHODS: A 9-part questionnaire was sent to 90 ordinary members of the Vascular Surgical Society of Great Britain and Ireland (VSS-GBI). Names and addresses were selected by highlighting every fourth ordinary member from the UK, in the 2000 VSS-GBI handbook. Ordinary members of the VSS-GBI who were clearly radiologists were excluded. RESULTS: Of the 90 questionnaires sent, 60 were returned (66.67%). The majority of respondents used both duplex and venography (61%) as the major investigative tools though some employed duplex only (17%). Multimodality treatment (radiological and operative) was the favoured approach. Only 17% still favoured conservative management alone. Thrombolysis was the most common intervention (86.7%) usually followed by elective thoracic outlet decompression. Most favoured a delayed approach for surgery of 6-12 weeks. First rib resection was the most commonly performed operation (58%), usually by the transaxillary approach (55%). Most of the respondents were doubtful of the role of stenting in this condition and did not use it. CONCLUSIONS: There is no definite consensus on treatment of this condition in the UK. A majority tend to favour a multimodal approach. Thrombolysis is the most common form of treatment employed and first rib resection via the transaxillary approach remains the most popular surgical procedure. The lack of consensus of this potentially disabling condition highlights the need for randomised clinical trials to guide management. PMID:15005942

    Highlights: • We evaluate operational municipal solid waste incinerators in the UK. • The supply chain of four case study plants are examined and compared in detail. • Technical, financial and operational data has been gathered for the four plants. • We suggest the best business practices for waste incinerators. • Appropriate strategy choices are the major difficulties for waste to energy plants. - Abstract: The uptake in Europe of Energy from Waste (EfW) incinerator plants has increased rapidly in recent years. In the UK, 25 municipal waste incinerators with energy recovery are now in operation; however, their waste supply chains and business practices vary significantly. With over a hundred more plant developments being considered it is important to establish best business practices for ensuring efficient environmental and operational performance. By reviewing the 25 plants we identify four suitable case study plants to compare technologies (moving grate, fluidised bed and rotary kiln), plant economics and operations. Using data collected from annual reports and through interviews and site visits we provide recommendations for improving the supply chain for waste incinerators and highlight the current issues and challenges faced by the industry. We find that plants using moving grate have a high availability of 87–92%. However, compared to the fluidised bed and rotary kiln, quantities of bottom ash and emissions of hydrogen chloride and carbon monoxide are high. The uptake of integrated recycling practices, combined heat and power, and post incineration non-ferrous metal collections needs to be increased among EfW incinerators in the UK. We conclude that one of the major difficulties encountered by waste facilities is the appropriate selection of technology, capacity, site, waste suppliers and heat consumers. This study will be of particular value to EfW plant developers, government authorities and researchers working within the sector of waste

    In the UK, as elsewhere, there is potential to improve how radiological challenges are addressed through improvement in, or development of, a strong radiation protection (RP) safety culture. In preliminary work in the UK, two areas have been identified as having a strong influence on UK society: the healthcare and nuclear industry sectors. Each has specific challenges, but with many overlapping common factors. Other sectors will benefit from further consideration.In order to make meaningful comparisons between these two principal sectors, this paper is primarily concerned with cultural aspects of RP in the working environment and occupational exposures rather than patient doses.The healthcare sector delivers a large collective dose to patients each year, particularly for diagnostic purposes, which continues to increase. Although patient dose is not the focus, it must be recognised that collective patient dose is inevitably linked to collective occupational exposure, especially in interventional procedures.The nuclear industry faces major challenges as work moves from operations to decommissioning on many sites. This involves restarting work in the plants responsible for the much higher radiation doses of the 1960/70s, but also performing tasks that are considerably more difficult and hazardous than those original performed in these plants.Factors which influence RP safety culture in the workplace are examined, and proposals are considered for a series of actions that may lead to an improvement in RP culture with an associated reduction in dose in many work areas. These actions include methods to improve knowledge and awareness of radiation safety, plus ways to influence management and colleagues in the workplace. The exchange of knowledge about safety culture between the nuclear industry and medical areas may act to develop RP culture in both sectors, and have a wider impact in other sectors where exposures to ionising radiations can occur.

    Even though mankind has evolved in a naturally radioactive environment, the existence of radiation was only discovered about a century or so ago. Since then the use of radioactive materials has grown rapidly and they are now used extensively in hospitals for medical diagnosis and treatment, and in general industry where they are used for measurement and inspection, as well as by the nuclear power industry, research laboratories and defence establishments. Like virtually all of man`s activities, the use of radioactive materials inevitably leads to the production of unwanted waste by-products, some of which will be radioactive. These radioactive wastes can be found in many different solid, liquid or gaseous forms and the radioactivity can range from such low levels that it is radiologically insignificant to levels that could cause death on direct exposure to it. To give a general indication of the levels of radioactivity, the wastes in the UK are usually grouped into three broad categories: (1) Low level waste (LLW): the least radioactive category; (2) Intermediate level waste (ILW); (3) High level waste (HLW): the most radioactive category. This waste is so highly radioactive that it generates significant quantities of heat and it is therefore also sometimes referred to as Heat Generating Waste. Radioactive wastes are produced by many industries in the UK although the majority both in terms of volume and radioactivity content comes from the civil nuclear power industry. This chapter concentrates on describing the way solid radioactive wastes are managed by the UK nuclear industry, within the Governments`s overall policy framework. It includes a description of the types and quantities of waste to be managed, current practices including the disposal of LLW, and plans for a deep repository for both ILW and LLW. 12 refs., 7 figs., 2 tabs.

  1. Measurement and modelling of methane fluxes from UK peatlands

    NASA Astrophysics Data System (ADS)

    Levy, P. E.; Gray, A.

    2012-12-01

    Nearly 5000 chamber measurements of CH4 flux were collated from 21 sites across the UK, covering a range of soil and vegetation types, to derive a parsimonious model that explains as much of the variability as possible, with the least input requirements. Less than half of the observed variability in instantaneous fluxes could be explained by the independent variables measured. Measurement error is one reason for this, and here we analyse several of the uncertainties inherent in these measurements, including the choice of model used to calculate the flux. Other reasons include the stochastic nature of some of the transport processes and the poor correspondence between the independent variables measured and the actual variables influencing the processes underlying methane production, transport and oxidation. Alternative measurement methods are considered which may circumvent some of these problems. When temporal variation was removed, and the fluxes averaged at larger spatial scales, simple models explained up to ~75 % of the variance in CH4 fluxes. Soil carbon, peat depth, soil moisture and pH together provided the best sub-set of explanatory variables. To estimate the impact of changes in peatland water table on CH4 emissions in the UK, an emission factor of +0.4 g CH4 m-2 y-1 per cm increase in water table was derived from the data. As an alternative approach, vegetation species composition provides a long-term integrator of environmental conditions, which may correlate with methane flux. Here, we used a "weighted averaging" approach to predict methane flux from plant species composition at a range of sites in the UK, continental Europe and Canada. Species were classified into functional groups, defined by a number of qualitative traits considered relevant to methane dynamics. We compared the results based on this functional classification with those based on the original species composition data with a purely taxonomic classification.

    Semiconductor research has formed the basis of many technological advances over the past 50 years, and the field is still highly active, as new material systems and device concepts are developed to address new applications or operating conditions. In addition to the development of traditional semiconductor devices, the wealth of experience with these materials also allows their use as an ideal environment for testing new physics, leading to new classes of devices exploiting quantum mechanical effects that can also benefit from the advantages of existing semiconductor technology in scalability, compactness and ease of mass production. This special issue features papers arising from the UK Semiconductors 2012 Conference, held at the University of Sheffield. The annual conference covers all aspects of semiconductor research, from crystal growth, through investigations of the physics of semiconductor structures to realization of semiconductor devices and their application in emerging technologies. The 2012 conference featured over 150 presentations, including plenary sessions on interband cascade lasers for the 3-6 µm spectral band, efficient single photon sources based on InAs quantum dots embedded in GaAs photonic nanowires, nitride-based quantum dot visible lasers and single photon sources, and engineering of organic light-emitting diodes. The seven papers collected here highlight current research advances, taken from across the scope of the conference. The papers feature growth of novel nitride-antimonide material systems for mid-infrared sources and detectors, use of semiconductor nanostructures for charge-based memory and visible lasers, optimization of device structures either to reduce losses in solar cells or achieve low noise amplification in transistors, design considerations for surface-emitting lasers incorporating photonic crystals and an assessment of laser power convertors for power transfer.

    This article discusses some of the specific challenges related to the management of diabetes in patients of South Asian origin. Communicating information that considers cultural, religious and language differences is important to promote effective self-management. The South Asian population in the UK is at greater risk of developing type 2 diabetes, and cultural practices such as fasting if not managed properly can lead to deterioration in their condition. The use of appropriate information and educators with Asian language skills and an understanding of the local population's culture are important to improve self-management of diabetes in these patients.

    Extracorporeal membrane oxygenation (ECMO) is needed for a small number of sick infants, children and adults who fail to respond to maximum ventilator therapy and pharmacological support. As the technology continues to develop, indications for early treatment with ECMO increase and the prognosis improves. Admission to a specialist unit is required during therapy, but essential intensive care needs remain as they would for any critically ill child. Attentive communication with, and support for, families are more important than ever. The publication of this article was delayed until after the announcement of the NHS Safe and Sustainable review of children's cardiac surgical services in the UK.

    These guidelines are an update for 2015 of the 2008 UK guidelines for the management of syphilis. The writing group have piloted the new BASHH guideline methodology, notably using the GRADE system for assessing evidence and making recommendations. We have made significant changes to the recommendations for screening infants born to mothers with positive syphilis serology and to facilitate accurate and timely communication between the teams caring for mother and baby we have developed a birth plan. Procaine penicillin is now an alternative, not preferred treatment, for all stages of syphilis except neurosyphilis, but the length of treatment for this is shortened. Other changes are summarised at the start of the guideline.

    Many people with life-limiting disease are vulnerable to emotional distress associated with physical, spiritual, psychological and social stressors. Psychological stress and affective disorders have the potential to influence decision making, particularly at the end of life. This article discusses the main reasons why assisted suicide and physician-assisted suicide (PAS) should remain illegal in the UK. In particular, it explores the problems associated with safeguarding 'vulnerable' patient groups and assessing mental capacity. The article also examines guidance for nurses regarding what to do if a patient asks for assistance to die or for information on assisted suicide and PAS. PMID:22272539

  11. Ammonia emissions from non-agricultural sources in the UK

    NASA Astrophysics Data System (ADS)

    Sutton, M. A.; Dragosits, U.; Tang, Y. S.; Fowler, D.

    A detailed literature review has been undertaken of the magnitude of non-agricultural sources of ammonia (NH 3) in the United Kingdom. Key elements of the work included estimation of nitrogen (N) excreted by different sources (birds, animals, babies, human sweat), review of miscellaneous combustion sources, as well as identification of industrial sources and use of NH 3 as a solvent. Overall the total non-agricultural emission of NH 3 from the UK in 1996 is estimated here as 54 (27-106) kt NH 3-N yr -1, although this includes 11 (6-23) kt yr -1 from agriculture related sources (sewage sludge spreading, biomass burning and agro-industry). Compared with previous estimates for 1990, component source magnitudes have changed both because of revised average emissions per source unit (emission factors) and changes in the source activity between 1990 and 1996. Sources with larger average emission factors than before include horses, wild animals and sea bird colonies, industry, sugar beet processing, household products and non-agricultural fertilizer use, with the last three sources being included for the first time. Sources with smaller emission factors than before include: land spreading of sewage sludge, direct human emissions (sweat, breath, smoking, infants), pets (cats and dogs) and fertilizer manufacture. Between 1990 and 1996 source activities increased for sewage spreading (due to reduced dumping at sea) and transport (due to increased use of catalytic converters), but decreased for coal combustion. Combined with the current UK estimates of agricultural NH 3 emissions of 229 kt N yr -1 (1996), total UK NH 3 emissions are estimated at 283 kt N yr -1. Allowing for an import of reduced nitrogen (NH x) of 30 kt N yr -1 and deposition of 230 kt N yr -1, these figures imply an export of 83 kt NH 3-N yr -1. Although export is larger than previously estimated, due to the larger contribution of non-agricultural NH 3 emissions, it is still insufficient to balance the UK

    A gridded 0.25° reconstruction of rainfall kinetic energy (RKE) over the UK, on the basis of pluviometric observations and reanalysis back to 1765, shows that autumn RKE doubled in 1991-2013 (˜2 MJ m-2) compared to 1948-1990 (˜1 MJ m-2). A shift eastward is underway, which includes southern and northern portions of the country. Analyzing the long-running England and Wales precipitation series, we conclude that it is likely that increased precipitation amounts associated with more frequent convective storms created conditions for higher energy events.

    British Nuclear Fuels plc (BNFL) operate a site for the disposal of Low Level Radioactive Waste at Drigg in West Cumbria, in North-West England. HMIP are responsible for the regulation of the site with regard to environmental discharges of radioactive materials, both operational and post-closure. This paper is concerned with post-closure matters only. Two post-closure performance assessments have been carried out for this site: one by the National Radiological Protection Board (NRPB) in 1987; and a subsequent one carried out on behalf of HMIP, completed in 1991. Currently, BNFL are preparing a Safety Case for continued operation of the Drigg site, and it expected that the core of this Case will comprise BNFL`s own analysis of post-closure performance. HMIP has developed procedures for the assessment of this Case, based upon experience of the previous Drigg assessments, and also upon the experience of similar work carried out in the assessment of Intermediate Level Waste (ILW) disposal at both deep and shallow potential sites. This paper describes the more important features of these procedures.

    Objective: Workforce planning reports identify a staff shortfall that jeopardizes the ability of UK radiotherapy centres to meet future demands. Obtaining an understanding of the work experiences of radiotherapy professionals will support the development of strategies to increase job satisfaction, productivity and effectiveness. Methods: A quantitative survey assessed job satisfaction, attitudes to incident reporting, stress and burnout, opportunities for professional development, workload, retention and turnover. Clinical oncologists were not included, as the Royal College of Radiologists, London, UK, had recently assessed their members' satisfaction. All questions were taken from validated instruments or adapted from the “UK National Health Service Staff Survey”. Results: The survey yielded 658 completed responses (approximately 16% response rate), from public and private sectors. Over a third (36%) of respondents were classified as satisfied for job satisfaction with 11% dissatisfied and the remaining 53% ambivalent. A significant proportion of clinical staff (37.5%) report high emotional exhaustion. Presenteeism was an issue with 42.4% attending work despite feeling unable to fulfil their role. Conclusion: Radiotherapy professionals are prone to the effects of compassion fatigue and burnout. Attention must be paid to workload and its impact on practitioners' job satisfaction. Professional development that is supported and informed by a performance development review is a simple and effective means of enhancing satisfaction. Individuals have a responsibility to themselves and their colleagues as their behaviours and attitudes influence job satisfaction. Advances in knowledge: This work identifies areas for future research to enhance the professional resilience of practitioners, in order to provide high-quality treatments. PMID:24786316

    A Register of HIV-infected persons who have had a negative antibody test within 3 years of their first antibody positive test (seroconverters) is being set up in the UK to monitor the distribution of times from HIV seroconversion to AIDS (the incubation period) and to death. It will also provide a national resource for use by those designing studies in this group of individuals. Clinicians caring for HIV-positive persons in Genito-Urinary Medicine, Infectious Disease and other departments throughout the UK were asked to participate by providing information on eligible subjects. Most laboratories undertaking HIV antibody testing were also contacted and asked to provide the name of the attending clinician for all seroconverters identified through the HIV laboratory reporting systems of the PHLS Communicable Disease Surveillance Centre (CDSC) and the Scottish Centre for Infection and Environmental Health (SCIEH) and for any other seroconverters known to them but not identified by CDSC or SCIEH. Data items sought for the Register include: sex, ethnic group, probable route of HIV transmission, annual CD4 counts, details of therapy and prophylaxis prescribed, AIDS-defining events and vital status. Follow up information is collected annually. Wherever possible, all seroconverters known to a clinic have been identified, whether currently alive or dead, either from clinic records or laboratory reporting or both. The objective is to establish and update a complete register of seroconverters on a long-term to basis to provide reliable estimates of the incubation period on which future projections of AIDS cases in the UK can be made.

    The homicide statistics of a popular UK television fictional crime series and the former Lothian & Borders police force region, Scotland were compared. This comparison was used to consider the implications for public attitudes which may influence the adoption of public health interventions to reduce homicide. 217 homicides were identified by 105 perpetrators in the television series 'Midsomer Murders' between 1997 and 2011; these were compared to 55 homicides by 53 perpetrators in the regional sample between 2006 and 2011. The numbers of serial killings (p < 0.0001), planned homicides, female perpetrators (p < 0.0001), shootings (p = 0.0456) and poisonings (p = 0.0289) were higher in the fictional sample. Lothian & Borders cases were almost all single killings, mostly unplanned, with a far greater rate of homicide by kitchen knives (p < 0.0001) and hitting/kicking (p = 0.0005) by intoxicated perpetrators. Control of access to pointed kitchen knives by members of certain groups may reduce homicide rates. If the popular perception of UK homicides is influenced by popular culture, the importance of such a public health intervention may not be apparent. PMID:24661708

    Space agencies such as NASA and ESA have ambitious long-term programmes that mark the beginning of a new era in space exploration where humans will land on Mars; an era requiring public support and, therefore, more consideration for public opinion. Empirical research shows that there are substantial differences in the level of understanding of space exploration among the general public. Studying audiences appears to be crucial to inform public engagement and communication strategies as well as policy debate. This paper presents the results of a survey conducted in the UK in 2008 at two science outreach events, the Royal Society Exhibition in London and the National Space Centre in Leicester, to investigate the motivations, beliefs, political preferences and attitudes towards space exploration of this audience. A sample of 744 respondents was collected. The analysis shows that the British public who come to outreach and engagement activities support space exploration but have some reservations about considering the advancement of UK space activities to be of national interest. Yet, when asked about means of exploring space, the majority agrees that space should be explored using both mankind and machines, ranking "generating new scientific knowledge and advancing human culture" as the most important reason for continuing investment in space research. Although the greater number of supporters says that more than the current government funding should be allocated to civil space activities, concerns about risk and value appear to influence this view.

    A number of medical smartphone applications have been developed to assist clinical oncology specialists. Concerns have arisen that the information provided may not be under sufficient scrutiny. This study aims to analyse the current applications available for clinical oncologists in the UK. Applications aimed specifically at physician clinical oncologists were searched for on the major smartphone operating systems: Apple iOS; Google Android; Microsoft Windows OS; and Blackberry OS. All applications were installed and analysed. The applications were scrutinised to assess the following information: cost; whether the information included was referenced; when the information was last updated; and whether they made any reference to UK guidelines. A novel rating score based on these criteria was applied to each application. Fifty applications were identified: 24 for Apple's iOS; 23 for Google's Android; 2 for Blackberry OS; and 1 for Windows OS. The categories of applications available were: drug reference; journal reference; learning; clinical calculators; decision support; guidelines; and dictionaries. Journal reference and guideline applications scored highly on our rating system. Drug reference application costs were prohibitive. Learning tools were poorly referenced and not up-to-date. Smartphones provide easy access to information. There are numerous applications devoted to oncology physicians, many of which are free and contain referenced, up-to-date data. The cost and quality of drug reference and learning applications have significant scope for improvement. A regulatory body is needed to ensure the presence of peer-reviewed, validated applications to ensure their reliability. PMID:24903139

    INTRODUCTION Providing nutrition for patients following pancreaticoduodenectomy (PD) is vital but can be challenging. Due to the lack of UK national guidelines for the provision of nutrition and nutritional pre-operative assessment regarding PD, a national survey was conducted. PATIENTS AND METHODS A questionnaire was sent to the Department of Nutrition and Dietetics at each of the 31 specialist pancreatic centres listed with the Pancreatic Society of Great Britain and Ireland. Questions were asked regarding the nutritional assessment and treatment of patients undergoing classical PD and pylorus-preserving PD (PPPD) resections. RESULTS Twenty-two centres responded to the questionnaire. With regard to PD and PPPD, 82% routinely feed patients following resection, 32% have a regimen for staring feeds, 18% carry out pre-operative nutritional assessment, five centres have funding for an hepatobiliary dietition, and only four centres have a specialist hepatobiliary dietition employed. There was no consensus regarding the type or route of feeding, and at least one centre reported using parenteral nutrition exclusively. CONCLUSIONS Very few centres in the UK have funding for a hepatobiliary dietition. Hence pre-operative nutritional assessment in patients undergoing PD and PPPD does not receive much input. Although the importance of postoperative feeding in these patients is appreciated in all major units, there is no consensus with regards to feeding regimens. The authors hope this observational study will address these issues with this important message and stimulate further study in this area. PMID:19409147

    The Solar Terrestrial Energy Programme (STEP) aims to improve our general understanding of how mass, energy and momentum are transformed between the various regions that form the Solar Terrestrial environment. STEP began in 1990 and will continue until 1997, during which time a number of major new spacecraft and ground-based projects will become operational. Six Working Groups form the basis of STEP, covering topics such as the Sun as a source of energy and disturbance, energy and mass transfer through the interplanetary medium and the magnetosphere-ionosphere system, ionosphere-thermosphere coupling and response to energy and momentum inputs, middle atmosphere responses to forcing from above and below, solar variability effects in the human environment, and informatics. A Royal Astronomical Society Geophysics Discussion meeting took place in March 1992 to draw to the attention of UK scientists the diverse nature of STEP and the opportunities offered by STEP. This paper consists of individual sections prepared by the speakers at the meeting and which cover most of the STEP Working Group topics. The main aims of each section are to provide a benchmark' for the present status of the research area and to look ahead to the possible contributions that UK scientists can make during STEP.

  5. Prevention and early detection of cervical cancer in the UK.

    Foran, Claire; Brennan, Arthur

    This literature review explores the prevention and early detection of cervical cancer in the UK. Current findings indicate that there is a risk for women under the age of 25 years, who may develop cervical cancer. There appears to be a gap in UK policy that may overlook these women, who are beneath the age for initial screening but exceed the age for vaccination. Despite the inextricable link between sexual activity and cervical cancer, cervical screening and sexual health promotion still appear to be disjointed, and the role of a sexually transmitted infection leading to the development of cervical cancer has not been emphasised enough in public health messages. Further training should be provided and its impact monitored, designed to address this anomaly in health promotion. There are many barriers to health promotion including, those of a societal, cultural and religious nature. Additional research is required to ascertain the types of educational and awareness interventions that would be most effective in promoting and encouraging positive sexual behaviours among young people, and to explore how these might be successfully implemented.

  6. Mapping an index of extreme rainfall across the UK

    NASA Astrophysics Data System (ADS)

    Faulkner, D. S.; Prudhomme, C.

    Distance from the sea, proximity of mountains, continentality and elevation are all useful covariates to assist the mapping of extreme rainfalls. Regression models linking these and other variables calculated from a digital terrain model have been built for estimating the median annual maximum rainfall, RMED. This statistic, for rainfall durations between 1 hour and 8 days, is the index variable in the rainfall frequency analysis for the new UK Flood Estimation Handbook. The interpolation of RMED between raingauge sites is most challenging in mountainous regions, which combine the greatest variation in rainfall with the sparsest network of gauges. Sophisticated variables have been developed to account for the influence of topography on extreme rainfall, the geographical orientation of the variables reflecting the prevailing direction of rain-bearing weather systems. The different processes of short and long-duration extreme rainfall are accounted for by separate regression models. The technique of georegression combines estimates from regression models with a map of correction factors interpolated between raingauge locations using the geostatistical method of kriging, to produce final maps of RMED across the UK.

  7. Ethnicity and Occupational Pension Membership in the UK

    PubMed Central

    2015-01-01

    Abstract Reflecting a relatively low‐value Basic State Pension, occupational pensions have historically been a key aspect of pension protection within Britain. Existing research shows that minority ethnic groups are less likely to benefit from such pensions and are more likely to face poverty in later life, as a result of the interaction of their labour market participation and pension membership patterns. However, the lack of adequate data on ethnic minorities has so far prevented the direct comparison of different ethnic groups, as well as their comparison to the White British group. Using data from the UK Household Longitudinal Study, this article explores patterns of employment and the odds ratios of membership in an employer's pension scheme among working‐age individuals from minority ethnic groups and the White British population, taking into account factors not used by previous research, such as one's migration history and sector of employment (public/private). The analysis provides new empirical evidence confirming that ethnicity remains a strong determinant of one's pension protection prospects through being in paid work, being an employee and working for an employer who offers a pension scheme. However, once an individual is working for an employer offering a pension scheme, the effect of ethnicity on that person's odds of being a member of that scheme reduces, except among Pakistani and Bangladeshi individuals for whom the differentials remain. The article also provides evidence on the pension protection of Polish individuals, a relatively ‘new’ minority group in the UK. PMID:27563161

    The aim of this study was to provide two-dimensional (2D) and M-mode echocardiographic reference ranges from a sample of the UK population of donkeys including geriatrics (>30 years), owned by The Donkey Sanctuary, and to assess the influence of gender, weight and age on these variables. A total of 36 donkeys with no clinical or echocardiographic evidence of cardiovascular disease were examined; 24 geldings and 12 females, aged 3-45 years old, weighing 130-262 kg. Left atrial to aortic ratio was larger in geldings (P=0.004). There was no significant difference for left ventricular M-mode diastolic diameter between females and geldings (P=0.121) after exclusion of one heavy female outlier. 2D measurements significantly increased with bodyweight including maximal left atrial diameter (R(2)=0.112; P=0.046), aortic diameter at various levels (e.g. annulus: R(2)=0.35; P<0.001) and the pulmonary artery diameter (R(2)=0.124; P=0.035). M-mode measurements were not significantly influenced by weight other than the left ventricular free wall in systole (R(2)=0.118; P=0.041). Age and heart rate did not have any significant effect on echocardiographic variables. This is the first UK study to report on echocardiographic reference ranges of sedentary donkeys across a wide age range and shows differences compared with reference ranges from working donkeys.

    Structured Abstract Objectives To describe the perceptual speech outcomes from the Cleft Care UK (CCUK) study and compare them to the 1998 Clinical Standards Advisory Group (CSAG) audit. Setting and sample population A cross-sectional study of 248 children born with complete unilateral cleft lip and palate, between 1 April 2005 and 31 March 2007 who underwent speech assessment. Materials and methods Centre-based specialist speech and language therapists (SLT) took speech audio–video recordings according to nationally agreed guidelines. Two independent listeners undertook the perceptual analysis using the CAPS-A Audit tool. Intra- and inter-rater reliability were tested. Results For each speech parameter of intelligibility/distinctiveness, hypernasality, palatal/palatalization, backed to velar/uvular, glottal, weak and nasalized consonants, and nasal realizations, there was strong evidence that speech outcomes were better in the CCUK children compared to CSAG children. The parameters which did not show improvement were nasal emission, nasal turbulence, hyponasality and lateral/lateralization. Conclusion These results suggest that centralization of cleft care into high volume centres has resulted in improvements in UK speech outcomes in five-year-olds with unilateral cleft lip and palate. This may be associated with the development of a specialized workforce. Nevertheless, there still remains a group of children with significant difficulties at school entry. PMID:26567854

  10. Human rights and patients' privacy in UK hospitals.

    2001-05-01

    The European Convention on Human Rights has been incorporated into UK domestic law. It gives many rights to patients within the National Health Service (NHS). This article explores the concept of patients' right to privacy. It stresses that privacy is a basic human right, and that its respect by health professionals is vital for a patient's physical, mental, emotional and spiritual well-being. I argue that health professionals can violate patients' privacy in a variety of ways. For example: the right to enjoy their property; the right to protect their medical and personal information as confidential; the right to expect treatment with dignity during intimate care; and the right to control their personal space and territory. Some preliminary evidence indicates that many health care practitioners, including nurses, are presently unaware of the articles of the Convention and the implications of the Human Rights Act 1998. In order to prevent litigation for breaches of patients' privacy, it is advocated that universities and other educational institutions, the Government and NHS trusts should help to produce a clear educational strategy and protocols so that students and practitioners are well informed in this field. Although 41 European countries are presently the signatories of the European Convention on Human Rights, including the UK, it is important to stress that the principles discussed in this article are applicable world-wide.

This comparison was used to consider the implications for public attitudes which may influence the adoption of public health interventions to reduce homicide. 217 homicides were identified by 105 perpetrators in the television series 'Midsomer Murders' between 1997 and 2011; these were compared to 55 homicides by 53 perpetrators in the regional sample between 2006 and 2011. The numbers of serial killings (p < 0.0001), planned homicides, female perpetrators (p < 0.0001), shootings (p = 0.0456) and poisonings (p = 0.0289) were higher in the fictional sample. Lothian & Borders cases were almost all single killings, mostly unplanned, with a far greater rate of homicide by kitchen knives (p < 0.0001) and hitting/kicking (p = 0.0005) by intoxicated perpetrators. Control of access to pointed kitchen knives by members of certain groups may reduce homicide rates. If the popular perception of UK homicides is influenced by popular culture, the importance of such a public health intervention may not be apparent.

    The uptake in Europe of Energy from Waste (EfW) incinerator plants has increased rapidly in recent years. In the UK, 25 municipal waste incinerators with energy recovery are now in operation; however, their waste supply chains and business practices vary significantly. With over a hundred more plant developments being considered it is important to establish best business practices for ensuring efficient environmental and operational performance. By reviewing the 25 plants we identify four suitable case study plants to compare technologies (moving grate, fluidised bed and rotary kiln), plant economics and operations. Using data collected from annual reports and through interviews and site visits we provide recommendations for improving the supply chain for waste incinerators and highlight the current issues and challenges faced by the industry. We find that plants using moving grate have a high availability of 87-92%. However, compared to the fluidised bed and rotary kiln, quantities of bottom ash and emissions of hydrogen chloride and carbon monoxide are high. The uptake of integrated recycling practices, combined heat and power, and post incineration non-ferrous metal collections needs to be increased among EfW incinerators in the UK. We conclude that one of the major difficulties encountered by waste facilities is the appropriate selection of technology, capacity, site, waste suppliers and heat consumers. This study will be of particular value to EfW plant developers, government authorities and researchers working within the sector of waste management. PMID:23978558

    To establish the current status of canine hydrotherapy in the UK and to ascertain information regarding the current use of hydrotherapy, a questionnaire was sent to 152 hydrotherapy centres throughout the UK, from which 89 responded. Hydrotherapy was found to be a rapidly growing business. Stand-alone centres were in existence; however, many centres were connected to other businesses, including boarding kennels and general practice veterinary surgeries. The dogs using the facility were mainly pedigree breeds, particularly labrador retrievers (30 per cent), and the most commonly encountered conditions were rupture of the cranial cruciate ligament (25 per cent), hip dysplasia (24 per cent) and osteoarthritis (18 per cent). The proportion of qualified versus unqualified staff varied between centres, highlighting a need for improved regulation of this aspect of the industry. However, all the dogs treated by the hydrotherapy centres surveyed were direct veterinary referrals, suggesting a good degree of professionalism in the field and a high regard for the benefits of hydrotherapy.

  14. UK medicines policy: the role of clinical pharmacologists.

    2012-06-01

    Clinical pharmacologists are the only medical specialists whose training focuses specifically on the safe, effective and cost-effective use of medicines, underpinned by an understanding of drug discovery, drug regulation, pharmacology, translational medicine and the performance of clinical trials. This unique perspective has allowed them to provide expertise and leadership in medicines regulation, medicines policy, health technology assessment and drug pricing. Clinical pharmacologists assisted in the creation of the Committee on Safety of Medicines (now the Commission on Human Medicines), the Yellow Card Scheme, the National Institute of Health and Clinical Excellence (NICE) and related organizations in Scotland and Wales, and contributed to clinical guidelines (through the Scottish Intercollegiate Guidelines Network) and the British National Formulary. Their research work has contributed substantially, through translational medicine and therapeutics, to the development of new medicines and, as a result, creation of health and wealth in the UK. Their work in medicines policy has served to protect patients from harms associated with the use of medicines. A reduction in the number of able junior doctors attracted to a career in clinical pharmacology, a reduction in the number of training posts, and an ageing population of academic trainers, puts the future of the specialty, and its contribution to patient safety and UK wealth creation, at substantial risk. Urgent measures are needed to convince the NHS and government that these essential skills should be protected and nurtured.

    Objective To qualitatively assess the discharge processes and postdischarge care in the community for infants discharged after congenital heart interventions in the first year of life. Design Qualitative study using semistructured interviews and Framework Analysis. Setting UK specialist cardiac centres and the services their patients are discharged to. Subjects Twenty-five cardiologists and nurses from tertiary centres, 11 primary and secondary health professionals and 20 parents of children who had either died after discharge or had needed emergency readmission. Results Participants indicated that going home with an infant after cardiac intervention represents a major challenge for parents and professionals. Although there were reported examples of good care, difficulties are exacerbated by inconsistent pathways and potential loss of information between the multiple teams involved. Written documentation from tertiary centres frequently lacks crucial contact information and contains too many specialist terms. Non-tertiary professionals and parents may not hold the information required to respond appropriately when an infant deteriorates, this contributing to the stressful experience of managing these infants at home. Where they exist, the content of formal ‘home monitoring pathways’ varies nationally, and families can find this onerous. Conclusions Service improvements are needed for infants going home after cardiac intervention in the UK, focusing especially on enhancing mechanisms for effective transfer of information outside the tertiary centre and processes to assist with monitoring and triage of vulnerable infants in the community by primary and secondary care professionals. At present there is no routine audit for this stage of the patient journey. PMID:26826171

    Predictive linear regression (LR) modelling between bioaccessible arsenic (B-As) and a range of total elemental compositions and soil properties was executed in order to assess the potential for developing a national B-As dataset for the UK. LR indicates that total arsenic (As) is the only highly significant independent variable for estimating B-As in urban areas where it explains 75-92% of the variance. The broad compatibility of the London, Glasgow and Swansea regression models suggests that application of these models to estimate bioaccessible As in UK soils impacted by diffuse anthropogenic urban contamination and non-ferrous metal processing should be relatively accurate. In areas dominated by Jurassic ironstones and associated clays and limestones, total As, P and pH are significant, accounting for 53, 14 and 5%, respectively, of the B-As variance. Models based on total As as the sole predictor in the combined Jurassic and Cretaceous sedimentary ironstones datasets explain about 40% of the B-As variance. The median As bioaccessible fraction (%As-BAF) is 19 to 28% in the anthropogenic contamination impacted urban domains, but much lower (5-9%) in geogenic terrains dominated by ironstones. Results of this study can be used as part of a lines of evidence approach to localised risk assessment but should not be used to replace bioaccessibility testing at individual sites where local conditions may vary considerably from the broad overview presented in this study.

    We investigate if there is a causal link between education and health knowledge using data from the 1984/85 and 1991/92 waves of the UK Health and Lifestyle Survey (HALS). Uniquely, the survey asks respondents what they think are the main causes of ten common health conditions, and we compare these answers to those given by medical professionals to form an index of health knowledge. For causal identification we use increases in the UK minimum school leaving age in 1947 (from 14 to 15) and 1972 (from 15 to 16) to provide exogenous variation in education. These reforms predominantly induced adolescents who would have left school to stay for one additionally mandated year. OLS estimates suggest that education significantly increases health knowledge, with a one-year increase in schooling increasing the health knowledge index by 15% of a standard deviation. In contrast, estimates from instrumental-variable models show that increased schooling due to the education reforms did not significantly affect health knowledge. This main result is robust to numerous specification tests and alternative formulations of the health knowledge index. Further research is required to determine whether there is also no causal link between higher levels of education - such as post-school qualifications - and health knowledge. PMID:25459203

    Despite media and public perception to the contrary cancer surgery is the most important modality for the control and cure of cancer. However, after years of underinvestment by research funders and increasing service delivery demands the academic cancer surgeon is an endangered species. In an effort to improve evidence-based policymaking in this critical domain of cancer research the ECRM has conducted a semi-quantitative assessment of the state of academic cancer surgery in the UK. We have found that the percentage of investment in cancer surgical technologies R&D is less than 1% and even when this is extended to other diseases then this figure is still less than 1%. A decline in the overall numbers of academic surgical staff is paralleled by our finding that over 50% of the academic cancer surgeons in this survey had insufficient time for research. With clinical trials and surgical technology development identified as key research domains the majority (60-80%) did not perceive any benefit for surgical research in these areas as a result of the creation of the UK National Cancer Research Institute. We also found high support for academic surgery from colleagues but medium-low support from many institutions. Key policy conclusions are: (1) greater hypothecated investment by research funders, particularly for the development of surgical technologies as well as clinical trials, and (2) the creation of cancer surgery centres of excellence which have sufficient staffing and institutional support to engendered a creative academic environment.

  20. Dynamical controls on estuarine bathymetry: Assessment against UK database

    2006-06-01

    New theories for estuarine bathymetry provide formulations for: (1) depth at the mouth, D versus river flow, Q; (2) tidal intrusion length L versus D and Z (tidal amplitude) and (3) a zone of morphological existence, delineated on a framework of Z versus D. Here, these theories are assessed against a database for 80 UK estuaries. Overall there is good agreement between theory and observations for the sizes and shapes of estuaries classified as either 'Coastal Plain' or 'Bar Built'. Likewise, most estuaries are shown to lie within the theoretical 'zone of bathymetric existence'. These encouraging agreements enable the theories to be used to: (1) enhance our understanding of existing morphologies, (2) identify anomalous estuaries and (3) make future predictions regarding likely impacts from global climate change and related management scenarios. Subsequent examination of regional historical patterns of morphological evolution, introducing detailed local knowledge, should help to explain these anomalies and refine the new theories. By 2100, we anticipate changes in UK estuaries due to ('precautionary') projected 25% changes in river flow of: Order (0.5-5 km) in lengths and Order (50-250 m) in breadths. Corresponding changes due to a projected sea level rise of 50 cm are increases in both lengths of Order (1-2.5 km) and breadths of Order (70-100 m). In both cases, the bigger changes will occur in larger estuaries.

    Ombrotrophic peatlands across northern latitudes represent a globally-important store for carbon (C), nitrogen (N) and phosphorus (P) through the Holocene. A key characteristic of ombrotrophic bogs is that N, P and other elements vital to their biogeochemical functioning are almost exclusively supplied by hydrological and biological inputs from the atmosphere. While different mechanisms regulating the atmospheric supply of N and P and their limiting effects on bog productivity have been widely studied, limited attention has been paid to the long-term patterns of, and controls on, macronutrient accumulation, cycling and stoichiometry in ombrotrophic peatlands. Indeed there is a dearth of C, N and P stoichiometric data from the UK despite decades of peatland research. Using data from 15 sites, we report the first estimates of millennial-scale macronutrient concentrations and accumulation rates in UK ombrotrophic peats. Carbon, nitrogen and phosphorus concentrations were measured on cores from five ombrotrophic blanket mires, spanning 4000-10000 years to present, and integrated with existing nutrient profiles from ten Scottish sites. Long-term C, N and P concentrations for the UK are 55.1, 1.55 and 0.037 wt%, similar to the few existing northern and tropical comparable sites worldwide. The uppermost peat (0 - 0.2 m) is more enriched in P and N (51.0, 1.86, and 0.070 wt%), while the deeper peat (0.5 - 1.25 m) is more depleted (56.6, 1.39, and 0.028 wt%). Long-term average (whole core) accumulation rates of carbon, nitrogen and phosphorus are 25.3±2.2 gC m-2 yr-1, 0.70±0.09 gN m-2 yr-1 and 0.018±0.004 gP m-2 yr-1, again similar to values reported elsewhere in the world. A number of significant findings can be drawn from our results: i) N and P concentrations in ombrotrophic peat are strongly associated, such that a regression model of N concentration on P concentration and mean annual precipitation, based on global meta data for surface peat samples, can explain 54

A key characteristic of ombrotrophic bogs is that N, P and other elements vital to their biogeochemical functioning are almost exclusively supplied by hydrological and biological inputs from the atmosphere. While different mechanisms regulating the atmospheric supply of N and P and their limiting effects on bog productivity have been widely studied, limited attention has been paid to the long-term patterns of, and controls on, macronutrient accumulation, cycling and stoichiometry in ombrotrophic peatlands. Indeed there is a dearth of C, N and P stoichiometric data from the UK despite decades of peatland research. Using data from 15 sites, we report the first estimates of millennial-scale macronutrient concentrations and accumulation rates in UK ombrotrophic peats. Carbon, nitrogen and phosphorus concentrations were measured on cores from five ombrotrophic blanket mires, spanning 4000-10000 years to present, and integrated with existing nutrient profiles from ten Scottish sites. Long-term C, N and P concentrations for the UK are 55.1, 1.55 and 0.037 wt%, similar to the few existing northern and tropical comparable sites worldwide. The uppermost peat (0 - 0.2 m) is more enriched in P and N (51.0, 1.86, and 0.070 wt%), while the deeper peat (0.5 - 1.25 m) is more depleted (56.6, 1.39, and 0.028 wt%). Long-term average (whole core) accumulation rates of carbon, nitrogen and phosphorus are 25.3±2.2 gC m‑2 yr‑1, 0.70±0.09 gN m‑2 yr‑1 and 0.018±0.004 gP m‑2 yr‑1, again similar to values reported elsewhere in the world. A number of significant findings can be drawn from our results: i) N and P concentrations in ombrotrophic peat are strongly associated, such that a regression model of N concentration on P concentration and mean annual precipitation, based on global meta data for surface peat samples, can

    The commissioning and provision of healthcare, including mental health services, must be consistent with ethical principles - which can be summarised as being "fair", irrespective of the method chosen to deliver care. They must also provide value to both patients and society in general. Value may be defined as the ratio of patient health outcomes to the cost of service across the whole care pathway. Particularly in difficult times, it is essential to keep an open mind as to how this might be best achieved. National and regional policies will necessarily vary as they reflect diverse local histories, cultures, needs and preferences. As systems of commissioning and delivering mental health care vary from country to country, there is the opportunity to learn from others. In the future international comparisons may help identify policies and systems that can work across nations and regions. However a persistent problem is the lack of clear evidence over cost and quality delivered by different local or national models. The best informed economists, when asked about the international evidence do not provide clear answers, stating that it depends how you measure cost and quality, the national governance model and the level of resources. The UK has a centrally managed system funded by general taxation, known as the National Health Service (NHS). Since 2010, the UK's new Coalition* government has responded by further reforming the system of purchasing and providing NHS services - aiming to strengthen choice and competition between providers on the basis of quality and outcomes as well as price. Although the present coalition government's intention is to maintain a tax-funded system, free at the point of delivery, introducing market-style purchasing and provider-side reforms to encompass all of these bring new risks, whilst not pursuing reforms of a system in crisis is also seen to carry risks. Competition might bring efficiency, but may weaken cooperation between providers

    Objectives With health inequalities high on the policy agenda, this study measures oral health inequalities in the UK. Methods We compare an objective clinical measure of oral health (number of natural teeth) with a self-reported measure of the impact of oral health (the Oral Health Impact Profile, OHIP) to establish whether the type of measure affects the scale of inequality measured. Gini coefficients and Concentration Indices (CIs) are calculated with subsequent decompositions using data from the 1998 UK Adult Dental Health Survey. Because the information on OHIP is only available on dentate individuals, analyses on the number of natural teeth are conducted for two samples – the entire sample and the sample with dentate individuals only, the latter to allow direct comparison with OHIP. Results We find considerable overall pure oral health inequalities (number of teeth: Gini = 0.68 (including edentate), Gini = 0.40 (excluding edentate); OHIP: Gini = 0.33) and income-related inequalities for both measures (number of teeth: CI = 0.35 (including edentate), CI = 0.15 (excluding edentate); OHIP: CI = 0.03), and the CI is generally higher for the number of teeth than for OHIP. There are differences across age groups, with CI increasing with age for the number of teeth (excluding edentate: 16–30 years: CI = 0.01, 65 + years: CI = 0.11; including edentate: 16–30 years: CI = 0.01, 65 + years: CI = 0.19). However, inequalities for OHIP were highest in the youngest age group (CI = 0.05). Number of teeth reflects the accumulation of damage over a lifetime, while OHIP records more immediate concerns. Conclusions There are considerable pure oral health inequalities and income-related oral health inequalities in the UK. Using sophisticated methods to measure oral health inequality, we have been able to compare inequality in oral health with inequality in general health. The results provide a benchmark for future comparisons but also indicate that the type of health
